T
he Antennas Direct UHF/VHF
antenna combiner allows you to join
a UHF antenna and a VHF antenna
with much lower insertion loss than a
conventional splitter.
There are also filters on each input
to prevent frequency overlap between
both antennas, avoiding possible
phase cancellation.
Helpful Tips:
•
If your cable run is greater than 75’, A pre-amplifier may be required.
•
UHF signals are line of sight. Get as much
elevation as practical.
•
Attic Installations will cut 40% -50% of
your signal strength.

Gain and S11 vs Frequency
Gain
is a measure of an antenna’s
ability to concentrate radiated
power from a particular direction.
Unlike other antennas that claim
high peak values, The gain of the
C1 is not only extremely high but
nearly uniform across the DTV
spectrum
S11
The method used to compute
losses from impedance mismatches.
The lower the number, the better.
The efficiency of an antenna is how
much signal received by the anten-
na actually makes it to the cable.
The C5 is an extremely efficient
antenna.
At its optimum frequency, the
mismatch loss for the C5 is very low
- less than .1 dB.
