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 bay and below the bottom bay for to protect from pattern interference by other antennas.
Antenna wind load is calculated for 100 Mph (160Km/h) per EIA-222-C standard.
