Channel Master CM 7777 Titan2 VHF/UHF
Preamplifier with Power Supply
The Titan range of mast mounted amplifiers has
been completely reengineered and updated. These amplifiers
represent the ultimate in preamplifier performance. They are
designed for use as an ultra low noise, ultra high gain
preamplifier for deepest fringe applications and MATV headend
applications.
Their very high signal handling also makes them suitable for use
as a mast mounted, ultra low noise distribution amplifier for
use in small MATV systems. All models feature 75 ohm, input and
output connections in line with modern headend engineering
practice.

(over 90% of digital TV signals are in the UHF band). The 4221
is optimized for "near-fringe" reception of HDTV. Its
space-efficient design is suitable for roof and attic
installations. 
The
4228 is optimized for "deep-fringe" reception of HDTV ！ it's one
of the highest-gain antennas available. This is a highly
directional design that will provide best results when most or
all of the desired stations are transmitting from the same
location.
