| TV Antenna Preamplifier Information
The
TV
Antenna preamplifier is most useful to 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.
It is also useful to maintain the strength of the signal as it travels
through coaxial cable because signals received by your TV antenna become weaker as they travel through coax cable and the longer the journey, the weaker the signal becomes.
If your local broadcast stations are not transmitting strong signals, a
preamplifier is almost necessary if you want to receive a clear signal
by the time it reaches your television.
Out
preamplifier units consist of an amplifier housing unit which is
mounted on the antenna mast and a power supply which is installed
indoors. This power supply unit is connected to the outdoor unit via
coaxial cable, which powers the outdoor booster. The connection between
these two units acts as a two way stream, proving voltage to the
booster will passing through digital signals.
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. |
