ClearStream2 Gain and VSWR 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 C2
is not only extremely high but nearly uniform across the
DTV spectrum
VSWR ( Voltage Standing Wave Ratio) The method used to compute
losses from impedance mismatches. The lower the number, the
better. If the VSWR = 1 then there is no loss.
The efficiency of an antenna is how much signal received
by the antenna actually makes it to the cable. The C2 is
an extremely efficient antenna. At its optimum frequency,
the mismatch loss for the C2 is very low - less than .1 dB.
ClearStream2
Horizontal Plane Reception Patterns
The ClearStream2 has very forgiving aiming characteristics
with more than 70 degrees of beamwidth across the main lobe
as well as a powerful secondary rear lobe. This allows the
C2 to receive signals from multiple directions with a single
fixed installation.
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.
- KEEP
ANTENNA AWAY FROM POWER LINES
