General Preamplifier Information
The TV Antenna preamplifier is useful for persons unable to view channels due to weak signal. The preamplifier will boost the signal received by the antenna making it much stronger by the time it reaches your TV set.
The Channel Master preamplifier is a two part unit, an outdoor amplification unit which is mounted on the mast of your antenna system and an indoor unit which powers the outdoor amplification unit. The indoor unit is stationed indoors and connects to the outdoor unit via coaxial cable.
If you already have an antenna set up and are considering adding a preamplifier to boost your signal strength. You would only need two additional short length coaxial runs, one from the antenna output to the preamplifier input (which should be no more than 5 feet) and one from the indoor power-supply to your TV set. You would simply use the current longer coaxial run to connect from the mast mounted units output to the indoor units input.
