Small satellite

Satellites of low mass and size, usually under 500 kg

A small satellite, miniaturized satellite, or smallsat is a satellite of low mass and size, usually under 1,200 kg (2,600 lb).[1] While all such satellites can be referred to as “small”, different classifications are used to categorize them based on mass. Satellites can be built small to reduce the large economic cost of launch vehicles and the costs associated with construction. Miniature satellites, especially in large numbers, may be more useful than fewer, larger ones for some purposes – for example, gathering of scientific data and radio relay. Technical challenges in the construction of small satellites may include the lack of sufficient power storage or of room for a propulsion system.

Rationales [ edit ]
Group name[2] Mass (kg) Extra Heavy satellite > 7,000 Heavy satellite 5,001 to 7,000 Large satellite 4,201 to 5,000 Large satellite 4,201 to 5,400 Intermediate satellite 2,501 to 4,200 Medium satellite 1,201 to 2,500 Small satellite 601 to 1,200 Mini satellite 201 to 600 Micro satellite 11 to 200 Nano satellite 1.1 to 10 Pico satellite 0.1 to 1 Femto satellite <0.1 One rationale for miniaturizing satellites is to reduce the cost; heavier satellites require larger rockets with greater thrust that also have greater cost to finance. In contrast, smaller and lighter satellites require smaller and cheaper launch vehicles and can sometimes be launched in multiples. They can also be launched 'piggyback', using excess capacity on larger launch vehicles. Miniaturized satellites allow for cheaper designs and ease of mass production. Another major reason for developing small satellites is the opportunity to enable missions that a larger satellite could not accomplish, such as: Constellations for low data rate communications Using formations to gather data from multiple points In-orbit inspection of larger satellites University-related research Testing or qualifying new hardware before using it on a more expensive spacecraft History [ edit ] The nanosatellite and microsatellite segments of the satellite launch industry have been growing rapidly in recent years. Development activity in the 1–50 kg (2.2–110.2 lb) range has been significantly exceeding that in the 50–100 kg (110–220 lb) range.[3] In the 1–50 kg range alone, fewer than 15 satellites were launched annually in 2000 to 2005, 34 in 2006, then fewer than 30 launches annually during 2007 to 2011. This rose to 34 launched in 2012 and 92 launched in 2013.[3] European analyst Euroconsult projects more than 500 smallsats being launched in 2015–2019 with a market value estimated at US$7.4 billion.[4] By mid-2015, many more launch options had become available for smallsats, and rides as secondary payloads had become both greater in quantity and easier to schedule on shorter notice.[5] Classification groups [ edit ] Small satellites [ edit ] The term "small satellite",[3] or sometimes "minisatellite", often refers to an artificial satellite with a wet mass (including fuel) between 100 and 500 kg (220 and 1,100 lb),[6][7] but in other usage has come to mean any satellite under 500 kg (1,100 lb).[4] Small satellite examples[according to whom?] include Demeter, Essaim, Parasol, Picard, MICROSCOPE, TARANIS, ELISA, SSOT, SMART-1, Spirale-A and -B, and Starlink satellites.[citation needed] Small satellite launch vehicle [ edit ] Although smallsats have traditionally been launched as secondary payloads on larger launch vehicles, a number of companies currently are developing or have developed launch vehicles specifically targeted at the smallsat market. In particular, the secondary payload paradigm does not provide the specificity required for many small satellites that have unique orbital and launch-timing requirements.[8] Companies offering smallsat launch vehicles include: Microsatellites [ edit ] The term "microsatellite" or "microsat" is usually applied to the name of an artificial satellite with a wet mass between 10 and 100 kg (22 and 220 lb).[3][6][7] However, this is not an official convention and sometimes those terms can refer to satellites larger than that, or smaller than that (e.g., 1–50 kg (2.2–110.2 lb)).[3] Sometimes, designs or proposed designs from some satellites of these types have microsatellites working together or in a formation.[12] The generic term "small satellite" or "smallsat" is also sometimes used,[13] as is "satlet".[14] Examples: Astrid-1 and Astrid-2,[citation needed] as well as the set of satellites currently announced for LauncherOne (below)[13] In 2018, the two Mars Cube One microsats—massing just 13.5 kg (30 lb) each—became the first CubeSats to leave Earth orbit for use in interplanetary space. They flew on their way to Mars alongside the successful Mars InSight lander mission.[15] The two microsats accomplished a flyby of Mars in November 2018, and both continued communicating with ground stations on Earth through late December. Both went silent by early January 2019.[16] Microsatellite launch vehicle [ edit ] A number of commercial and military-contractor companies are currently developing microsatellite launch vehicles to perform the increasingly targeted launch requirements of microsatellites. While microsatellites have been carried to space for many years as secondary payloads aboard larger launchers, the secondary payload paradigm does not provide the specificity required for many increasingly sophisticated small satellites that have unique orbital and launch-timing requirements.[8] In July 2012, Virgin Galactic announced LauncherOne, an orbital launch vehicle designed to launch "smallsat" primary payloads of 100 kg (220 lb) into low Earth orbit, with launches projected to begin in 2016. Several commercial customers have already contracted for launches, including GeoOptics, Skybox Imaging, Spaceflight Industries, and Planetary Resources. Both Surrey Satellite Technology and Sierra Nevada Space Systems are developing satellite buses "optimized to the design of LauncherOne".[13] Virgin Galactic has been working on the LauncherOne concept since late 2008,[17] and as of 2015 , is making it a larger part of Virgin's core business plan as the Virgin human spaceflight program has experienced multiple delays and a fatal accident in 2014.[18] In December 2012, DARPA announced that the Airborne Launch Assist Space Access program would provide the microsatellite rocket booster for the DARPA SeeMe program that intended to release a "constellation of 24 micro-satellites (~20 kg (44 lb) range) each with 1-m imaging resolution."[19] The program was cancelled in December 2015.[20] In April 2013, Garvey Spacecraft was awarded a US$200,000 contract to evolve their Prospector 18 suborbital launch vehicle technology into an orbital nanosat launch vehicle capable of delivering a 10 kg (22 lb) payload into a 250 km (160 mi) orbit to an even-more-capable clustered "20/450 Nano/Micro Satellite Launch Vehicle" (NMSLV) capable of delivering 20 kg (44 lb) payloads into 450 km (280 mi) circular orbits.[21] The Boeing Small Launch Vehicle is an air-launched three-stage-to-orbit launch vehicle concept aimed to launch small payloads of 45 kg (100 lb) into low Earth orbit. The program is proposed to drive down launch costs for U.S. military small satellites to as low as US$300,000 per launch ($7,000/kg) and, if the development program was funded, as of 2012 could be operational by 2020.[22] The Swiss company Swiss Space Systems (S3) has announced plans in 2013 to develop a suborbital spaceplane named SOAR that would launch a microsat launch vehicle capable of putting a payload of up to 250 kg (550 lb) into low Earth orbit.[23] The Spanish company PLD Space born in 2011 with the objective of developing low cost launch vehicles called Miura 1 and Miura 5 with the capacity to place up to 150 kg (330 lb) into orbit.[24] Nanosatellites [ edit ] [25] Launched, planned and predicted nanosatellites as of August 2021 The term "nanosatellite" or "nanosat" is applied to an artificial satellite with a wet mass between 1 and 10 kg (2.2 and 22.0 lb).[3][6][7] Designs and proposed designs of these types may be launched individually, or they may have multiple nanosatellites working together or in formation, in which case, sometimes the term "satellite swarm"[26] or "fractionated spacecraft" may be applied. Some designs require a larger "mother" satellite for communication with ground controllers or for launching and docking with nanosatellites. Over 1600 nanosatellites have been launched as of August 2021.[27][25] A CubeSat[28] is a common type of nanosatellite,[25] built in cube form based on multiples of 10 cm × 10 cm × 10 cm, with a mass of no more than 1.33 kilograms (2.9 lb) per unit.[29] The CubeSat concept was first developed in 1999 by a collaborative team of California Polytechnic State University and Stanford University, and the specifications, for use by anyone planning to launch a CubeSat-style nanosatellite, are maintained by this group.[29] With continued advances in the miniaturization and capability increase of electronic technology and the use of satellite constellations, nanosatellites are increasingly capable of performing commercial missions that previously required microsatellites.[30] For example, a 6U CubeSat standard has been proposed to enable a satellite constellation of 35 8 kg (18 lb) Earth-imaging satellites to replace a constellation of five 156 kg (344 lb) RapidEye Earth-imaging satellites, at the same mission cost, with significantly increased revisit times: every area of the globe can be imaged every 3.5 hours rather than the once per 24 hours with the RapidEye constellation. More rapid revisit times are a significant improvement for nations performing disaster response, which was the purpose of the RapidEye constellation. Additionally, the nanosat option would allow more nations to own their own satellite for off-peak (non-disaster) imaging data collection.[30] As costs lower and production times shorten, nanosatellites are becoming increasingly feasible ventures for companies.[31] Example nanosatellites: ExoCube (CP-10), ArduSat, SPROUT[32] Nanosatellite developers and manufacturers include EnduroSat, GomSpace, NanoAvionics, NanoSpace, Spire,[33] Surrey Satellite Technology,[34] NovaWurks,[35] Dauria Aerospace,[36] Planet Labs[34] and Reaktor.[37] Nanosat market [ edit ] In the ten years of nanosat launches prior to 2014, only 75 nanosats were launched.[25] Launch rates picked up substantially when in the three-month period from November 2013–January 2014 94 nanosats were launched.[34] One challenge of using nanosats has been the economic delivery of such small satellites to anywhere beyond low Earth orbit. By late 2014, proposals were being developed for larger spacecraft specifically designed to deliver swarms of nanosats to trajectories that are beyond Earth orbit for applications such as exploring distant asteroids.[38] Nanosatellite launch vehicle [ edit ] With the emergence of the technological advances of miniaturization and increased capital to support private spaceflight initiatives in the 2010s, several startups have been formed to pursue opportunities with developing a variety of small-payload Nanosatellite Launch Vehicle (NLV) technologies. NLVs proposed or under development include: Actual NS launches: NASA launched three satellites on 21 April 2013 based on smart phones. Two phones use the PhoneSat 1.0 specification and the third used a beta version of PhoneSat 2.0 [42] ISRO launched 14 nanosatellites on 22 June 2016, 2 for Indian universities and 12 for the United States under the Flock-2P program. This launch was performed during the PSLV-C34 mission. ISRO launched 103 nanosatellites on 15 February 2017. This launch was performed during the PSLV-C37 mission.[43] Picosatellites [ edit ] The term "picosatellite" or "picosat" (not to be confused with the PicoSAT series of microsatellites) is usually applied to artificial satellites with a wet mass between 0.1 and 1 kg (0.22 and 2.2 lb),[6][7] although it is sometimes used to refer to any satellite that is under 1 kg in launch mass.[3] Again, designs and proposed designs of these types usually have multiple picosatellites working together or in formation (sometimes the term "swarm" is applied). Some designs require a larger "mother" satellite for communication with ground controllers or for launching and docking with picosatellites. Picosatellites are emerging as a new alternative for do-it-yourself kitbuilders. Picosatellites are currently commercially available across the full range of 0.1–1 kg (0.22–2.2 lb). Launch opportunities are now available for $12,000 to $18,000 for sub-1 kg picosat payloads that are approximately the size of a soda can.[44] Femtosatellites [ edit ] The term "femtosatellite" or "femtosat" is usually applied to artificial satellites with a wet mass below 100 g (3.5 oz).[3][6][7] Like picosatellites, some designs require a larger "mother" satellite for communication with ground controllers. Three prototype "chip satellites" were launched to the ISS on Space Shuttle Endeavour on its final mission in May 2011. They were attached to the ISS external platform Materials International Space Station Experiment (MISSE-8) for testing.[45] In April 2014, the nanosatellite KickSat was launched aboard a Falcon 9 rocket with the intention of releasing 104 femtosatellite-sized chipsats, or "Sprites".[46][47] In the event, they were unable to complete the deployment on time due to a failure of an onboard clock and the deployment mechanism reentered the atmosphere on 14 May 2014, without having deployed any of the 5-gram femtosats.[48] ThumbSat is another project intending to launch femtosatellites in the late 2010s.[49] ThumbSat announced a launch agreement with CubeCat in 2017 to launch up to 1000 of the very small satellites.[50][needs update] In March 2019, the CubeSat KickSat-2 deployed 105 femtosats[clarification needed] called "ChipSats" into Earth orbit. The satellites were tested for 3 days, and they then reentered the atmosphere and burned up.[51] Technical challenges [ edit ] Small satellites usually require innovative propulsion, attitude control, communication and computation systems. Larger satellites usually use monopropellants or bipropellant combustion systems for propulsion and attitude control; these systems are complex and require a minimal amount of volume to surface area to dissipate heat. These systems may be used on larger small satellites, while other micro/nanosats have to use electric propulsion, compressed gas, vaporizable liquids such as butane or carbon dioxide or other innovative propulsion systems that are simple, cheap and scalable. Small satellites can use conventional radio systems in UHF, VHF, S-band and X-band, although often miniaturized using more up-to-date technology as compared to larger satellites. Tiny satellites such as nanosats and small microsats may lack the power supply or mass for large conventional radio transponders, and various miniaturized or innovative communications systems have been proposed, such as laser receivers, antenna arrays and satellite-to-satellite communication networks. Few of these have been demonstrated in practice. Electronics need to be rigorously tested and modified to be "space hardened" or resistant to the outer space environment (vacuum, microgravity, thermal extremes, and radiation exposure). Miniaturized satellites allow for the opportunity to test new hardware with reduced expense in testing. Furthermore, since the overall cost risk in the mission is much lower, more up-to-date but less space-proven technology can be incorporated into micro and nanosats than can be used in much larger, more expensive missions with less appetite for risk. Collision safety [ edit ] Small satellites are difficult to track with ground-based radar, so it is difficult to predict if they will collide with other satellites or human-occupied spacecraft. The U.S. Federal Communications Commission has rejected at least one small satellite launch request on these safety grounds.[52] See also [ edit ]

Satellite dish

Type of parabolic antenna

A satellite dish is a dish-shaped type of parabolic antenna designed to receive or transmit information by radio waves to or from a communication satellite. The term most commonly means a dish which receives direct-broadcast satellite television from a direct broadcast satellite in geostationary orbit.

Principle of operation [ edit ]
Schematics of reflection principles used in parabolic antennas.

The parabolic shape of a dish reflects the signal to the dish’s focal point. Mounted on brackets at the dish’s focal point is a device called a feedhorn. This feedhorn is essentially the front-end of a waveguide that gathers the signals at or near the focal point and ‘conducts’ them to a low-noise block downconverter or LNB. The LNB converts the signals from electromagnetic or radio waves to electrical signals and shifts the signals from the downlinked C-band and/or K u -band to the L-band range. Direct broadcast satellite dishes use an LNBF, which integrates the feedhorn with the LNB. A new form of omnidirectional satellite antenna, which does not use a directed parabolic dish and can be used on a mobile platform such as a vehicle was announced by the University of Waterloo in 2004.[1]
The theoretical gain (directive gain) of a dish increases as the frequency increases. The actual gain depends on many factors including surface finish, accuracy of shape, feedhorn matching. A typical value for a consumer type 60 cm satellite dish at 11.75 GHz is 37.50 dB.

With lower frequencies, C-band for example, dish designers have a wider choice of materials. The large size of dish required for lower frequencies led to the dishes being constructed from metal mesh on a metal framework. At higher frequencies, mesh type designs are rarer though some designs have used a solid dish with perforations.

A common misconception is that the LNBF (low-noise block/feedhorn), the device at the front of the dish, receives the signal directly from the atmosphere. For instance, one BBC News downlink shows a “red signal” being received by the LNBF directly instead of being beamed to the dish, which because of its parabolic shape will collect the signal into a smaller area and deliver it to the LNBF.[2]
Modern dishes intended for home television use are generally 43 cm (18 in) to 80 cm (31 in) in diameter, and are fixed in one position, for Ku-band reception from one orbital position. Prior to the existence of direct broadcast satellite services, home users would generally have a motorised C-band dish of up to 3 m in diameter for reception of channels from different satellites. Overly small dishes can still cause problems, however, including rain fade and interference from adjacent satellites.

Europe [ edit ]
In Europe, the frequencies used by DBS services are 10.7–12.75 GHz on two polarisations H (Horizontal) and V (Vertical). This range is divided into a “low band” with 10.7–11.7 GHz, and a “high band” with 11.7–12.75 GHz. This results in two frequency bands, each with a bandwidth of about 1 GHz, each with two possible polarizations. In the LNB they become down converted to 950–2150 MHz, which is the frequency range allocated for the satellite service on the coaxial cable between LNBF and receiver. Lower frequencies are allocated to cable and terrestrial TV, FM radio, etc. Only one of these frequency bands fits on the coaxial cable, so each of these bands needs a separate cable from the LNBF to a switching matrix or the receiver needs to select one of the 4 possibilities at a time.[citation needed]
Systems design [ edit ]
In a single receiver residential installation there is a single coaxial cable running from the receiver set-top box in the building to the LNB on the dish. The DC electric power for the LNB is provided through the same coaxial cable conductors that carry the signal to the receiver. In addition, control signals are also transmitted from the receiver to the LNB through the cable. The receiver uses different power supply voltages (13 / 18 V) to select vertical / horizontal antenna polarization, and an on/off pilot tone (22 kHz) to instruct the LNB to select one of the two frequency bands. In larger installations each band and polarization is given its own cable, so there are 4 cables from the LNB to a ‘multiswitch’ switching matrix, which allows the connection of multiple receivers to the multiswitch in a star topology using the same signalling method as in a single receiver installation.[citation needed]
Satellite finder [ edit ]
Sat finder

A satellite finder (or sat finder) is a satellite field strength meter used to accurately point satellite dishes at communications satellites in geostationary orbit.[3][4][5] Professional satellite finder meters allow better dish alignment and provide received signal parameter values as well.

Types [ edit ]
Motor-driven dish [ edit ]
A dish that is mounted on a pole and driven by a stepper motor or a servo can be controlled and rotated to face any satellite position in the sky. There are three competing standards: DiSEqC, USALS, and 36 V positioners. Many receivers support all of these standards.

Motor-driven dishes come in a variety of sizes, but a dish of at least 120 centimetres (47 in) is required to receive signals from distant satellites which are intended to serve other areas.[citation needed]
With DiSEqC and USALS, the satellite dish will automatically aim itself at one of sixteen satellites programmed in previously when pressing one of the channel buttons on the remote.[citation needed] Motor-driven satellite dishes using USALS can detect other satellites in a constellation after one has been found and aimed at.[citation needed]
Most receivers sold at present[when?] are compatible with USALS and DiSEqC 1.0 and 1.2.

u -band). Special dish for up to 16 satellite positions (K-band).

Every standard-size dish enables simultaneous reception from multiple different satellite positions without re-positioning the dish, just by adding additional LNB or using Special Duo LNB, Triple, or Four Feed Monoblock LNB.

However, some designs much more effectively optimize simultaneous reception from multiple different satellite positions without re-positioning the dish. The vertical axis operates as an off-axis concave parabolic concave hyperbolic[clarification needed] Cassegrain reflector, while the horizontal axis operates as a concave convex[clarification needed] Cassegrain. The spot from the main dish wanders across the secondary, which corrects astigmatism by its varying curvature. The elliptic aperture of the primary is designed to fit the deformed illumination by the horns. Due to double spill-over, this makes more sense for a large dish.

Switching between satellites is possible by using DiSEqC switches added to a satellite installation, or built-in Duo LNBs or Monoblock LNBs.

Most receivers sold presently[when?] are compatible with at least DiSEqC 1.0, which can switch automatically between 4 satellites (all of contemporary Monoblock LNBs) as the user changes channels using the remote control.

DiSEqC 1.1 allows for switching automatically between 16 satellite positions or more (through cascading switches).

Motor-driven dishes assure better optimal focusing for the given dish size; LNB is always in central alignment with the broadcasting satellite, but DiSEqC switches are faster than DiSEqC motors as no physical movement is required.[citation needed]
VSAT [ edit ]
A common type of dish is the very small aperture terminal (VSAT). This provides two way satellite Internet communications for both individuals and private networks for organizations. At present,[when?] most VSATs operate in K u band; C band is restricted to less populated regions of the world. In 2005, dish manufacturers began moving towards new K a band satellites operating at higher frequencies, offering greater performance at lower cost.[citation needed] These antennas vary from 74 to 120 cm (29 to 47 in) in most applications though C-band VSATs may be as large as 4 m (13 ft).

Geometry of offset parabolic antenna. The dish is an asymmetric segment of a paraboloid; the vertex of the paraboloid is below the bottom edge of the dish. The beam axis, which is aimed at the satellite, passes through the vertex and the focus, so the feed antenna at the focus is outside the beam.

Homemade dishes [ edit ]
Any metal surface which concentrates a significant fraction of the reflected microwaves at a focus can be used as a dish antenna, at a lower gain. This has led to trash can lids, woks, and other items being used as “dishes”. Only modern low noise LNBs and the higher transmission power of DTH satellites allows a usable signal to be received from such inefficient DIY antennas.

History [ edit ]
Parabolic antennas referred to as “dish” antennas had been in use long before satellite television. The term satellite dish was coined in 1978 during the beginning of the satellite television industry, and came to refer to dish antennas that send and/or receive signals from communications satellites. Taylor Howard of San Andreas, California, adapted an ex-military dish in 1976 and became the first person to receive satellite television signals using it.[6]
The first satellite television dishes were built to receive signals on the C-band analog, and were very large. The front cover of the 1979 Neiman-Marcus Christmas catalog featured the first home satellite TV stations on sale.[7] The dishes were nearly 20 feet (6.1 m) in diameter.[8] The satellite dishes of the early 1980s were 10 to 16 feet (3.0 to 4.9 m) in diameter[9] and made of fiberglass with an embedded layer of wire mesh or aluminium foil, or solid aluminium or steel.[10]
Satellite dishes made of wire mesh first came out in the early 1980s, and were at first 10 feet (3.0 m) in diameter. As the front-end technology improved and the noise figure of the LNBs fell, the size shrank to 8 feet (2.4 m) a few years later, and continued to get smaller reducing to 6 feet (1.8 m) feet by the late 1980s and 4 feet (1.2 m) by the early 1990s.[11] Larger dishes continued to be used, however.[11] In December 1988, Luxembourg’s Astra 1A satellite began transmitting analog television signals on the K u band for the European market.[12] This allowed small dishes (90 cm) to be used reliably for the first time.[12]
In the early 1990s, four large American cable companies founded PrimeStar, a direct broadcasting company using medium power satellites.[13] The relatively strong K u band transmissions allowed the use of dishes as small as 90 cm for the first time.[13] On 4 March 1996, EchoStar introduced Digital Sky Highway (Dish Network).[14] This was the first widely used direct-broadcast satellite television system and allowed dishes as small as 20 inches to be used. This great decrease of dish size also allowed satellite dishes to be installed on vehicles.[15] Dishes this size are still in use today. Television stations, however, still prefer to transmit their signals on the C-band analog with large dishes due to the fact that C-band signals are less prone to rain fade than K u band signals.[16]

How heavy are these large satellite dishes? (and tips on taking them down?)

Your in Luck

i do this all the time for a living

OK, this is what you need

1. Make sure you car has a Tow Bar

2. a Small Trailer and some rope

3. Yourself and a Freind or two (don’t do it on your own, Unless you’ve taken down at least 20 or so of these things and you know how to do it yourself…… I still use 2 Guys to take

Down C Band Dishes)

now, you have 2 ways to go about this

You can

1. Disassemble the entire dish and Support Post

or

2. You can Seperate the Dish itself from the support post

if you choose Number 2,

then.. Load the dish (Assebled) in the back of your trailer and secure it with the ropes

the rest of the stuff you can just throw in the trailer as well

if you choose to disassemble the whole thing

MAKE SURE YOU KNOW HOW TO RE-ASSEMBLE IT

to Disassemble it, You’ll need 2 Large Shift Spanners

Some Power Tools, Phillips Head bits etc

the first thing you do is take the dish down from the support stand, Cut the RG6 Cable that runs from the LNB to the Set Tob Box, before you take down the dish (or Just disconnect it from the LNB)

next.. on the ground disassemble it.

take off the LNB cover first (3 screws , Phillips head)

take off the LNB (3 Screws Phillips Head)

this will make the Dish Arms go Loose , Now remove them from the Dish

if it has it.. Remove the Centre Plate in the middle of the dish

Now remove the metal bit that holds the dish onto the pole from the back, You’ll need 2 big Adjustable wrenches

Next.. Disconnect the Wedges from Each other You’ll have about 6 or 8 wedges total

normally you need your cordless drill for this, it takes some time

and.. that’s pretty much it

re -assemble in reverse

Depending on Size, Let’s assume it’s a 1.8Metre Dish, You could be looking at about 50Kg or so

NOW .. CONSIDER THIS

if you take it down in high winds, Your going to have a problem… BE REALLY REALLY CARFEULL

if you drop it, and bend it, You can’t just bend it back into shape and expect it to be ok (doesn’t always work that way)

Use 2 or 3 guys, work Slowly and BE SAFE

the hardest part is..

1. When you first remove it from the pole, and you get that free fall feeling from the dish, of having no support………….. you need to control that with a few guys

2. Getting it to the ground (thankfully your not taking from a roof, therefore you don’t need to worry about your footing on roof tiles)

PM me if you need help with this

NOW. REGARDING RETUNING

You need to know what your doing

You need a Spectrum Analyzer (A Good One, not a shit one) that does DVB-S/DVB-S2

You need to know what satellite you want to point to

You need to know it’s geostationary orbital postion in the sky

you can look the satellite up on LYNGSAT

you need to know you LNB L.O. Frequency, Most Likely 5150

You need to know what Frequency you want to scan IN

you need to know Your Forward Error correction (FEC)

You need to know your symbol Rate

You need to know your Polarisation

You need to know how the spectrum looks in Vertical 13 Volts and in Horizontal 18 Volts , otherwise you’ll be crossed Polarised and wont know why you can’t get a signal

there’s a lot to it

and if you don’t have a spectrum analyzer, Your pretty much , shit out of luck

anyway, i hope this info helps you

if you have questions… AND I KNOW YOU WILL HAVE

PM Me

i’m happy to help

i have tonnes of experience in this field,

and unlike many others in this industry , i am one of the few who actually knows what to do , How to do it properly and i can explain anything to you,

good Luck
