These fiberglass enclosed antennas offer significant advantages over most exposed element arrays and deliver equal or better electrical performance. Commander Omni Antennas employ multiple, large diameter copper radiating elements stacked collinerly, fed in phase and enclosed in a weather-proof fiberglass housing. These DC grounded units use low loss Teflon and insulated connectors. The antenna provides 5.0 dBd gain and can withstand winds of 100 mph (160 km/hr). It is excellent for duplex systems with 8 MHz or less separation between Tx and Rx frequencies. Several mounting hardware options are available for these antennas.
