Installation Methods for Satellite TV Systems

The installation can be easy where the rear wall of the property faces south. The dish can be mounted directly to the wall by means of the bracket supplied by the dish manufacturer. In case the front wall of a house faces south, it is generally preferable to mount the dish on a side wall where it is less obvious. A stand-off bracket, if needed, incurs additional expense. In face the dish can not be mounted on the side where the satellite is obscured by trees or brickwork then it is necessary to stood up on a pole, using a strong stand-off bracket with sufficient supports to prevent movement in wind. The additional work and hardware can increase the installation cost considerably and the setup appearance may not be as neat but it is often better than having it on the front of the house to annoy your neighbors, city planning officer and as an invitation to every potential burglar who passes by. It can be avoid by clamped or piped it to a crumple tile or to a pole which extends through the roof tiles. In the final case, make absolutely certain that no rainwater will be kept on the dish! It's not really designed for mounting on the side of a house at 90 degrees without extra brackets. Beware of the roof overhang!

More Complex Installations
Normally the LNB only installed in one receiver. However, a special “Twin LNB” may be used to feed two receivers via two coaxial cables. This setup is often used to allow different satellite channels to be watched in separate rooms. The Twin output LNB may be used to connect to two receivers in the same house. A Twin LNB with just one shared dish may be economy for two households to watch satellite TV channels provided that the two receivers are fully isolated by an approved distribution box. The reason is that, if one receiver becomes ‘live’ then the other may also become ‘live’, unless it is isolated. A compromise would be to ground the dish by means of a thick copper cable to an earth rod. If you wish to see programs from another satellite, then it will be necessary to fit two LNBs to your dish. Because the dish can not point directly at both satellites at once, it is usually necessary to get a slightly larger dish to compensate for the “off the beam” signal. This arrangement is only assume that the two satellites are not located far apart from each other. With this arrangement you can watch all the TV channel from both satellites. To increase the number of LNB, you may need to get a Quad LNB output and setup as the same way as dual LNB as told in previous statement. To feed more than four you'll need a special Quattro LNB and an IF Distribution system –it is not cheap!

Trees in the way
Don’t neglect the tiny leaves on the tree. Tree leaves are very good at blocking microwaves. However, you may get good reception in winter if the trees are deciduous and lose their leaves in Autumn. Alignment of the dish is not easy without a meter and the trees will be giving the blockage trouble. Try it after the leaves have gone. If you get bad signal in Spring, you may have probably think of killing the trees to return your quality TV program. The law changed time to time and you can ask your local government to get the property owner to carry out the work at his expense. If he refuses, the government has the right to get the work done and to sue him for the cost. However, you don’t want to have a spat with a neighbor so discuss with him politely first. Usually it's not necessary to create a “hole sight ” more than the dish width but you'd have to make accurate measurements to decide where the hole needs to be and to keep it clear of leaves. If you can get a picture in winter then it may be reasonable to get someone to climb the tree with creating a fake disc size obstacle of your dish to block the signal. That way you'd know precisely where is the signal goes wrong. If you can move your dish to a different lateral position or a higher position then you might be able to save the trees. You are permitted to put a Dish network on a chimney without planning permission. Use a protractor and a weight on a string to check the satellite location relative to your dish position. Other solution include putting the Dish Network dish on a neighbor’s property, using a larger dish or mounting the dish on the other side to avoid the tree itself - sometimes possible if the tree trunk is large and the lowest branches aren’t too low..

Installation — Not So Easy As It Looks
Although everyone can install a system by themselves, because it is usually money well spend to employ an experienced installer. An installer is used to working safely at the top of a roof. He understands that a slight bend in a cable can distort the signal and ruin the picture quality. Even a seemingly simple task such binding the cable to a connector requires knowledge and skill. All connections must be made watertight and electrically secure. The installer will use expensive tighten tape or a weatherproof sleeve with waterproof silicone grease. Heaviest rain fall and the strongest ultraviolet radiation from the sun must be taken into consideration. Cheap PVC tape can only lasting until the next time it rains or the sun shines brightly. The installer should be fully equipped such as the powerful battery-operated drill, correct bit size and special bolt to clamp brackets securely to the wall. He must have the good technical skill to deliver good job by drilling through hard brick and soft plaster. Although it is possible to align the dish to the satellite by using a guesswork and hand carry TV, the installer will have the compass, inclinometer and professional signal strength meter (or spectrum analyzer) to do it professionally in seconds rather than days and nights. The crucial points, he will be familiar with the electronic integration satellite receiver and its controls. He will know how to tune your television and video recorder to receive the satellite programs clearly from the receiver and he will be able to give you training on the entire change control channel and make any necessary adjustments by yourself. Finally, if anything goes wrong, he is the one who has to climb the slippery ladder in pouring rain in the dark to settle the mess.
