| The Channel Master television
antenna booster (preamplifier) will amplify digital and HD signals
received by your antenna. This antenna amplifier is a
high gain, low noise preamplifier used for weak signal areas to allow a
weak signal that is present at the antenna to be amplified to a
viewable strength.
The CM 7778 preamp offers less gain than the CM 7777
but still has enough gain to get the signal from
the antenna to the TV set. This preamp is a perfect choice if you are
in a
strong to medium strength signal area but are still having troubles
receive the strongest signals. Preamplifier are also used if you
anticipate distributing your signal with a digital splitter to multiple
locations throughout your location as splitters reduce the signal
strength per output.
• VHF and UHF bands with separate amplification
• Gain: VHF 16 dB - UHF 23 dB
• Can be configured for separate or combined inputs
• Includes a switchable FM trap
• Outdoor rated housing
• Mast mounted amplification unit with indoor power supply which connect via coaxial cable
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.
