Values shown are typical. Actual values may vary with each specific installation. Attenuation of connecting cables not taken into
account. Gain will be affected if null fill, beam tilt, special H / V ratio or special wavelength spacing is required. Gain is provided for one
polarization and is equal in circularly polarized antennas for both horizontal and vertical components. If antenna is side mounted, the
supporting structure will have a slight effect on radiation pattern and on VSWR. Contact us with details of your installation for
customized data. (*)Total tower space recommended allows 5 ft (1.5 m) of clear tower space above and below the mounting area to
protect from pattern interference by other antennas. On multi-bay arrays, we suggest extending support pipe min. 5 ft (1.5 m) above the
top bay and below the bottom bay. Estimated wind loads are calculated w/o radome per EIA Standard RS-222-C for 100 mph (160 kph)
