This guide shows you in an easy-to-follow approach, how to select your dish, choose the best location, install, and eventually fine tune your satellite antenna for the best reception. Installation of the satellite dish itself and the Installation of an appropriate decoder to receive the television programming from your service provider. However, prior to moving on with this two-stage satellite TV installation process, you need to select and purchase a satellite TV kit. This consists of the satellite dish and related mounting kit, high-grade RF coaxial cable, and the satellite TV receiver, or decoder. TV programming you will be able to receive.
Equally important is deciding on the number of LNBs. LNBF are low noise ‘block’ down-converters. An LNBF is an LNB with an integrated feedhorn. Most LNB’s in use today are actually LNBF’s. The term ‘low noise’ relates to the quality of the amplification and mixing that takes place inside the LNB. LNB’s sit in front of the actual parabola of the dish, at the end of the arm projecting from the satellite dish.
Their purpose is to receive, amplify and down convert the required ‘blocks’ of microwave frequencies to lower 950MHz to 1. The number of LNB’s determines the number of satellites a satellite dish can ‘see’ since a separate LNB is required to receive signals from satellites in different orbital positions. Satellite TV service providers use multiple satellites to deliver their content – implying that multiple LNBs are required to receive all television programming supported by a satellite TV service provider. LNB’s use an antenna probe inside the feedhorn to pick up the signal focused by the satellite dish. Switching to the correct polarized probe is carried out electronically via a voltage sent up the coaxial cable by the receiver. Proper installation and adjustment of the feedhorn is critical to system performance. It is particularly important if you are installing a feedhorn that receives Ku-Band signals. In order to find the correct focal distance for tracking, the feedhorn must be at the correct distance from the center of the dish, properly oriented, centered and perpendicular to the plane of the antenna.
D ratio that is called for in the antenna specifications. D ratio yourself using a formula. 2 – Rotate the feed to it’s proper orientation using the “polar axis template”. The polar axis is a line that runs through the center of the dish pivot points. It is the axis around which the dish will rotate. 3 – Centering the feed in the dish is also critical to proper reception. The 3 measurements should be equal. The easiest way to check this is to use an inclinometer or universal protractor.
D on the feedhorn allows the feedhorn to take advantage of all of the signal being reflected off of the dish, without receiving interfering ground noise or terrestrial interference. When dealing with most prime focus antennas, the number should come out between . If you notice, most of those numbers are also on scale on the side of the feedhorn. What this adjustment actually does is determines how wide of an angle the feedhorn can “see”. 10ft diameter dish that is 24 in. 28 for example, then the focal distance is relatively short. When that is the case, the focal distance is often only a few inches greater than the depth of the dish. Therefore, the feed needs to be able to “see” nearly straight to the side of the opening in the throat.
10ft diameter dish that is 11 in. D ratio would be closer to . 42 and the focal distance would be much longer. In that case, the feed would need to have an narrower field of view so it would “see” the whole dish, yet not see past the edge of the dish. 416 which you would round up to give you a setting of . EXAMPLE: A dish with a .
D will have the throat about flush with the rings. Polarity problems are usually very easy to recognize. They are usually indicated by the fact that every other channel is bad. You will notice that on some satellites, only the even numbered channels will come in, while on other satellites only the odd numbered channels will come in. This happens because the probe inside the feedhorn will not turn the 90 degrees that is required to change from a horizontally polarized channel to a vertically polarized channel. 1 – Use a volt meter to check the voltage at the back of your receiver to make sure that the voltage is coming out of your receiver.
5 supply, so the voltage should be there as long as the receiver is turned ON. 2 – Check for dc voltage at the pulse connector. The pulse output is what tells the servo motor how far to turn the probe. 5v connectors, re-connect the wires that go to the dish. Then, go out to the dish and remove the feedhorn cover. Disconnect the 3 wires that are connected to the servo motor. 5 voltage on each respective wire. If you are NOT getting the same voltage as you had at the receiver, then you have a wiring problem.
4 – Have someone inside change channels on the satellite receiver. If the shaft pulls out, you will need to send the entire feed to repair. 5 – If the servo motor does not turn, and you have the correct voltages getting to the motor, that normally indicates that the motor is bad and needs to be replaced. You can usually purchase a servo motor at any satellite dealer. If you find that the servo motor seems to be buzzing all of the time or if you are watching a program that seems to fade out intermittently and will come back by itself or if you change the channel up or down and back, the problem is also likely to be a bad servo motor. 1 – Take the servo motor off of the feedhorn and hook it up directly to the back of your receiver. You must disconnect the wires going to the dish for this test to be valid. 2 – Watch the servo while you change channels, then let it sit for a couple of minutes.
If it turns when you change channels and does not drift or buzz when you are not changing channels, that tells you that the receiver and servo motor are working properly and the problem is likely to be noise being pick up by your unshielded pulse line. The only way to correct this problem is to make sure that the pulse line is shielded and the shield is grounded at one end. 3 – If the servo motor behaves the same way when it is hooked up directly behind the receiver as it did out at the dish, then it is most likely bad. We hope this information was helpful. If you can’t solve your polarity problem after following the instructions and tips above, we recommend calling out your local satellite dealer to troubleshoot the system further. Currently, DirecTV offers eight type of dishes while DISH Network has ten. Dishes range in size from 18-inch to 36-inch x 22-inch. However, more than the shape or size, the real significant difference between the various types of dishes relates to the number of LNBs, and the number of supported outputs.
LNBs and four outputs, with each of these LNBs pointing to a different satellite orbit. If you want to hook up more receivers than your dish can accommodate, you will have to use a multi-switch to split up the satellite feed without compromising signal quality. Some multi-switches allow you to add over-the-air broadcasts or cable feeds, and send both signals to each viewing area via a single coax cable. In this case, you will need a diplexer for each viewing area to split up the signals again. You cannot split a satellite TV signal through an ordinary RF splitter as used in terrestrial TV reception. As indicated earlier on, broadcast signals from satellites are split in two different polarizations, and these are differentiated at the LNB.
If signals with different polarization were sent over the cable at the same time, they would interfere with each other. A multi-switch works by taking the input from a dual LNB on the dish and then locks one of the LNB’s to always look at the even transponders while the other LNB to always look at the odd transponders on the satellite. The switch then has multiple outputs to receivers. A receiver connected to a multi-switch sends a switching signal back up the coax cable to enable the switch to select the correct LNB it needs to look at. In the case of multiple ‘dual LNBs’, the process is the same except that now, each of the LNBs will be looking at a different satellite. If your satellite dish was installed prior to October 2005, you would not be able to receive all DirecTV programming. If you don’t remember when your dish was installed or if you’re just not sure that it is a 5-LNB, take a look at your dish and see if it matches either one of the DirecTV satellite dish. If not, you will have to order a new dish.
These dishes are required to receive the new MPEG-4 local and national HD programming. Depending on the type of dish you have, you may need to install a second dish aimed at a different satellite to receive DISH Network HDTV service. With the slightly smaller 18-inch, you can only pick either one of these satellite slots. To receive all available DISH Network channels, including all high definition local and national channels from a single satellite dish, you need an MPEG-4 compatible dish antenna. Note: Deciding on the required number of LNBs, shape and size of your satellite dish, depends on a number of factors, including the area where you live, service provider, and programming package selected. This is something that is best decided after you speak with your digital satellite TV service provider. Now that you have made the plunge and purchased a satellite dish, you need to get that satellite TV antenna up so you can receive all the channels!

The relatively small size of present day digital satellite TV dish antenna systems means that these may be practically fixed just about anywhere. In particular, these compact satellite dishes are especially suitable for city dwellers. While you may choose to have your new satellite dish installed by a professional, yet the actual installation process is not difficult to do. The only real difficulty that may arise in the process is when aiming the dish to get the best signal from the satellites. This is a crucial step and it is this step which may warrant professional assistance. First, you have to decide on the exact location where best to install your satellite dish. There are a few issues that you need to take into account here. Remember that DSS satellites are in a geo-stationary orbit above the equator.
Therefore, a satellite dish must point due South when your position is located north of the equator and North if you are located south of the equator. Choose a location that is easily accessible in case you need to clean snow or debris out of your satellite dish, or to re-adjust the dish in case it has lost its alignment. A suitable location is to attach the dish to a post which has been sunken in the ground. The chosen location should be unobstructed by trees, branches, buildings, telephone lines, clotheslines, electrical wires, power lines, radio and television towers, etc. All are possible sources of interference. In other words, there must be no obstructions between the dish site and the satellites in the sky. Once you determines that the location is suitable, you will have to decide on a permanent or portable installation. Ideally, the selected location should be such as to allow you to take a route that is as straight and as close to your television set as possible.
Finally, refer to the included instructions for any specific details. Choose a method of installation that allows your system to withstand the elements year-round and still remain perfectly aligned and rigidly mounted. Remember that system movement can reduce signal reception to the point of complete loss. Always do a trial run on the ground for coax cable installation from the satellite dish to the place where it will enter your house. Make sure it is long enough to reach both points. Attach the cable to the satellite dish and then run it across your yard and into the house through a drilled hole.

I recommend that you place the receiver and a portable TV set near the dish for that you see a picture while make the adjusts. Attach the cable to your television set. Seal all outdoor electrical connections with weatherproof sealant, and bury the incoming receiving line below the frost line level. Determine which satellite carries your most frequently viewed programs. Locate the area outside your home that is nearest to your television set. Turn and face south – or north if you are located south of the equator. Look from east to west, following an arc that mimics the sun’s path across the sky.

We recommend that before going through the installation process, you cannot split a satellite TV signal through an ordinary RF splitter as used in terrestrial TV reception. If you want to see Sky channels without a dish currently — it looks almost like a round speaker or flashlight. Position the plate, place the metal plugs and hammer them into the wall. When a user terminates their contract with this provider, and this is one of the easiest parts to finish. You don’t need to call a professional installer.
As described above, observe any obstacles that may obscure the line of sight along the arc. This is the most critical step prior to installation. Satellite positions are given in orbit slot degree coordinates and are true, not magnetic locations. These slots will be based on an azimuth heading that must be viewed as true rather than a compass position. Since a compass will have a magnetic variation. Once you have managed to install your new satellite dish, you will surely want to get the maximum number of channels. There is only one way forward – get that satellite TV antenna tuned for perfect reception! The line-of-sight view to the particular satellite is free of obstacles and obstructions. The mast supporting the antenna is rigidly mounted and level.
Adjust the antenna reflector to azimuth angle obtained for the particular satellite. This adjustment is the east-west movement of the reflector on the mount and is given in azimuth degrees. This adjustment is from the horizon to the sky and is given as elevation in degrees from that point. Peak the signal to the highest scale at this point. Ideally, this should be done using a signal ‘strength’ meter due to the greater signal sensitivity of the latter. Lock the antenna azimuth adjustment on the mount once the signal level is maximized. Perform the same procedure as in steps 4 through 6, using the elevation adjustment, first up and then down for peaking.
Lock the satellite dish elevation at the point of maximum signal reception. Your dish should now be aligned and and with a good picture in screen. Look the quality picture in others channels and if necessary repeat the adjustments. Ground the antenna and the signal line entrance into the residence to electrical code standards as detailed above. Once ready, you can relax and enjoy your new system ! These satellite finders are really useful little helpers when it comes down to perfectly aligning a satellite dish. Meters are sensitive gauges the amount of signal coming from satellite. This sensitivity allows finding the sweet spot of the satellite dish. You can see that once the fine-tuning is finished, the signal level is again at the maximum.
Some people are trying to align their satellite dishes with the on-screen digibox signal bar which is way too slow, inaccurate and not sensitive enough for a good alignment. Keep in Mind: While installing your satellite dish yourself can save you money, yet it possible to enjoy a totally FREE satellite dish installation by a professional if you qualify for one of the promotional offers from DirecTV, DISH Network or other service provider.

For the first time ever, those who would previously have found themselves ineligible for Sky’s TV service now have the opportunity to use their broadband connection rather than the traditional satellite dish. Around two million potential customers are expected to be affected by the upcoming change. Currently, the only way a Sky PVR can receive all the various channels you subscribe to is via a satellite dish. No firm date has been given yet but, depending on how the roll-out fares in mainland Europe, late 2018 or even early 2019 seems to be most likely. Is Sky the best, or should you be looking elsewhere?
