Overview: The Channel Master Titan 2 Model CM-7777 Mast
Preamplifier provides amplification for HD and digital signals received by your antenna. Preamplifiers can also be
used when distributing the antenna signal to multiple TVs, as splitters reduce
the signal strength at each output. The preamplifier comes with an indoor power
supply, which connects via coaxial cable.
Signal Gain: The CM-7777 is a high gain, low noise
preamplifier to be used in weak signal areas to boost the antenna signal to a
viewable strength. The preamplifier provides 30 dB of signal gain on both VHF
and UHF bands, at frequencies between 54 MHz and 1002 MHz.
Warning: Because of the high gain output, the CM-7777 is
recommended for applications where ALL broadcast towers are 80+ miles away.
Just one high power signal or broadcaster in close proximity can cause
over-amplification, which can result in the loss of reception. For
98% of consumer applications, the
CM-7778 Medium Gain Preamplifier is recommended.
Switchable FM Trap: The amplifier has an FM trap to block FM
signals to prevent them from interfering with the TV signal. If you wish to
unblock the FM signals, you will need to remove the cover, held in place by 4
Phillips-head screws, and set the switch to "Out".
Case: The CM-7777 features a rugged, outdoor-rated housing
that can withstand temperatures up to 140°F. The preamplifier mounts to the
antenna mast with the supplied U-bolt assembly just below the antenna. The unit
mounts with the connections facing downward to keep moisture out of the housing
and the connections dry.
Note: The preamplifier and supplied U-bolt assembly are designed for use
with antenna masts up to 1-3/4" in diameter.
Connections: The CM-7777 has two F-type 75-ohm connections
at the preamplifier: a combined VHF/UHF input, and an output/power connection.
The indoor power supply (AC adapter) connects via coaxial cable, and includes a
power inserter to energize the mast-mounted amplifier along the cable.
