With a satellite television system you can get even more choices than with cable tv. Satellite tv system and programming deals give you up to 500 channels to watch.

In general, satellite tv has a lot of similarities to broadcast television. Satellite tv is just a wireless system that is used in order to deliver television programming directly to a consumers home. Broadcast television and satellite stations both send programming by way of a radio signal. Broadcast stations make use of anl antenna in order to send radio waves to the local area. You can pick up these signals with a smaller antenna that can be purchased from your local electronics store. The downside to broadcast television through the use of an antenna is range due to the fact that the radio signals are shot out from the broadcast antenna in a straight line. To receive these broadcast signals, you would need to be located within the direct line of sight of the antenna. With this type of broadcasting and reception, small objects like trees and buildings are not much of a problem. However, big obstacles, such as the Earth itself, can reflect those radio waves. If the Earth happened to be perfectly flat, you would be able to pick up these broadcast television signals thousands of miles from the main source. The problem with this is that our Earth is round. Because of this curvature, the line of site for this signal is eventually broken down.
