System and method for effective reception and transmission of satellite signals
First Claim
1. A system for terrestrial transmission of RF signals comprising:
- an antenna, where said antenna includes an active device and a passive device, where the passive device receives RF signals; and
a decoder connected to the antenna, where decoder receives and analyzes IF signals from said antenna and upon receipt the IF signals sends commands to the active device in order to maintain an acceptable IF signal.

Abstract
The present invention relates to a system and method for terrestrial transmission of RF signals comprising: an antenna, where said antenna includes an active device and a passive device and a decoder. The passive device receives RF signals and passes the signals to the active device. The active device includes at least one amplifier, where active device down converts the RF signals to IF signals and applies a gain to at least one of the RF signals and the IF signals. The decoder connects to the antenna, where decoder receives and analyzes the IF signals from said antenna and upon receipt of the IF signals sends commands to the active device in order to maintain an acceptable IF signal, where said commands instruct the active device to selectively adjust the gain.

36. A system for terrestrial transmission of RF signals comprising:
-
a plurality of antennas, where each antenna includes an active device and a passive device, where the passive device receives RF signals, and the active device down converts the RF signals to IF signals;
a plurality of master decoders, where each master decoder receives and analyzes the IF signals from each antenna and upon receipt of the IF signals sends commands to each respective active device in order to maintain an acceptable IF signal; and
a distribution switch, where said distribution switch receives each IF signal transmitted through each master decoder and transmits each IF signal to a plurality of end user decoders, where each end user decoder receives and analyzes the IF signals from said distribution switch and upon receipt of the IF signals sends commands to the distribution switch in order to maintain an acceptable IF signal. - View Dependent Claims (37, 38, 39, 40)
