Installing a Satellite Dish

If you've decided to switch to Satellite TV, you'll need to install your dish before you can start taking advantage of the varied programming and digital and HD picture quality.

Before starting, here are some safety tips to take into account:

1. If it's your first time, the process can take several hours. Be patient and don't try to rush things, as this can be dangerous and result in the dish not being installed correctly.

2. If it is wet or windy outside, don't try installing your dish. This is dangerous and not worth the risk.

3. If your dish is bigger than 80 centimeters, you shouldn't install it alone. Have someone assist you.

4. If you're using ladders, have someone hold them steady and spot you.

5. If you're installing the dish on a chimney, be careful of the chimney collapsing from wind load.

Once you have all the necessary tools assembled, several hours to work, and sunny weather with no wind, you're ready to begin mounting the dish. When installing your dish, it's important to make sure that it is mounted properly to ensure that the broadcast signals are received correctly. The broadcasts come from a geostationary satellite located 22,300 miles above the equator. That means that from the northern hemisphere, you'll need a clear view of the southern sky. The first thing you'll need to do is find out elevation and azimuth. Input your city, state, and satellite information to receive the satellite position, latitude, longitude, azimuth, elevation, and skew. Next you'll want to site the dish. Make sure there are no trees or obstructions blocking your dish's view of the satellite. Now you're ready to start mounting.

If you're mounting the dish on a flat beam or roof, then the base of the dish must be parallel to the mounting surface. If you're mounting the dish on a wall, you'll need to drill the wall for the dish mounting plates. Drill into strong brickwork to ensure that the dish doesn't fall off. The next thing you need to do is position the support pole. You might find it easiest to attach the dish (without the LNB) to the support pole before securing the pole. After bolting down the dish, adjust it so that the mast is exactly perpendicular to the level.

Once the dish is set properly, it has to be aimed towards the satellites. To do this, attach the receiver cables and LNB and connect everything to the decoder and your TV. At this point, the digital receiver must be connected to the TV, and both have to be turned on. To calculate the accurate signal strength, you'll someone to watch the signal strength screen on the digital receiver while you manipulate the signal by manually adjusting the position of the dish.

If this procedure does not result in a signal, re-check that the mount is perfectly level, that the cables are correctly connected to the receiver, and that the azimuth and elevation coordinates are precise. After a signal is found, fine-tune the dish to maximize signal strength. Loosen the bolts and slowly rotate the dish in the direction the signal was received until the maximum strength reading is reached. Once this has been achieved, tighten the bolts again and get ready to enjoy your new high-definition satellite TV.
