VSWR (Voltage Standing Wave Ratio)
This method is used to compute losses from
impedance mismatches. The lower the
number, the better. If the VSWR = 1 then
there is no loss.
The efficiency value of an antenna defines
how much signal received by the antenna
actually makes it to the cable. The C1 is an
extremely efficient antenna. At it’s optimum
frequency, the mismatch loss for the C1 is
very low (less than .1dB).
ClearStream 1™ Horizontal
Plane Reception Patterns
The ClearStream 1™ has very forgiving
aiming characteristics with more than 70
degrees of beamwidth across the primary
lobe, as well as a powerful secondary rear
lobe. This allows the C1 to receive signals
from mutiple 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.
ClearStream 1™ Gain and
VSWR vs. Frequency
Performance
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 it is nearly uniform
across the UHF DTV spectrum.
