Omnidirectional Antenna
The model S8964B omnidirectional antenna provides broadband transmission and reception of linearly polarized signals in the 896 to 960 MHz frequency band. The antenna provides good RF performance and coverage for trunking, alarm systems and telemetry applications. The antenna construction features a durable fiberglass radome to withstand harsh weather environments, and a plated copper laminated radiator to achieve high reliability, promoting a long life. The antenna has a 4 dBd gain with a nominal 25° x 64° half-power beamwidth and an SWR of less than 1.2 (max) on 50 W impedance. Standard models are white in color and mounting hardware is included.

2.4 GHz Omnidirectional Site Antenna
The OD series omnidirectional site antenna offers 12 dBi gain for use in ISM applications at 2.4 GHz. The unit comprises a collinear array with the radiation elements stacked vertically. This design maintains a circular pattern in the horizontal plane and compresses the vertical pattern to achieve higher gain. The free-space antenna can be mounted anywhere without a ground plane. A phasing element cancels undesirable out-of-phase currents, which results in improved bandwidth and minimized minor side lopes.

Wideband Transmit Antenna
The model BM-01 wideband transmit antenna is designed to cover frequencies from 25 to 1000 MHz. Measuring only 12" high, the antenna provides omnidirectional coverage in azimuth and a high power bandwidth of between 80° (25 MHz) and 40° (1000 MHz) in elevation. SWR is better than 3.5 across the band and power handling is available in 5, 100 and 1000 W. Gain is better than –20 dB from 25 to 249 MHz and better than 0 dB from 250 to 1000 MHz. Price: $850 for the 100 W unit (1–9).
