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.
