This beats running in and out of the house to see if you got the signal. Be sure to do it as the sun starts going down to make it easier to see the screen.
Bad signal or no signal in the majority of the cases means you are not getting the correct data stram or symbol rate from the satellite. That can be due to a number of reasons, the main one being the dish is not really aimed at the satellite you think it is. You can also have bad coax or a bad LNB, or even, gulp, a bad receiver. Since we test each receiver before we ship it, we have very few bad units go out to customers.
The secret to aiming the satellite dish is to first determine the elevation ( how high the dish faces up ) and the azimuth ( the direction the dish faces ) that you need to point the dish. There is no substitute for either accurately doing this, or having a lot of patience if you don't. If you don't know where to point the dish, you can spend weeks moving it all over the sky.
I would suggest that you try to figure out, either through us or someone you know, or via the net, what direction you need to aim the dish and make sure that you have a clear line of sight to the satellite.
Once you get the dish mounted and know the general direction, aim the dish VERY slowly. If you move too fast you may go right over the correct signal and never see the picture or on screen meters indicate anything. With Ku, 1/4 inch off is all it takes to loose a signal. So, move your dish about 1/4 inch and wait for a second or two. Then move it again. Go left to right, if you don't get it, move the elevation a tad and repeat the process.
One thing that can really get you when you are aiming the dish. Some of the MPEG-2 symbol rates are the same on different satellites, some of these satellites are side by side. You won't be the first person, myself included, to see a nice and strong signal and get no picture. You may be on the wrong satellite, it is a easy mistake.
Aiming of these FTA dishes is different from the little 18 inch dishes. The 18 inch dish does not require a lot of careful aim and the DSS satellites are more powerful than the FTA satellites. But then you pay monthly for all that stuff, right?
Thanks to those installers that can do this !
