Gain is provided for vertical polarization.
If the antenna is side mounted, the supporting
structure will have a slight effect on the
radiation pattern and VSWR.
Actual values vary with the specific installation.
Contact us for more details of your installation.
Five ft(1.6mt) of pipe required above the top
antenna and below the bottom antenna for to
protect from pattern interference by other
antennas.
Antenna wind load is calculated for 100 Mph
(160Km/h) per EIA-222-C standard.
