Omnidirectional antennas are offered with either a coaxial or rectangular waveguide interface. Omnidirectional antennas provide a complete azimuth coverage of 360˚ with ±1.0 dB angular gain flatness. These omnidirectional antennas cover a bandwidth of 10% and up to full waveguide band with unnoticeable performance degradation towards the higher and lower ends of the frequency range. They are also constructed with precisely machined housings and a protective radome to ensure a rugged mechanical configuration. The below standard offering covers the frequency range of 23 to 100 GHz, but custom frequencies can be requested. The listed models are only offered with a waveguide interface. While most models offer a fixed vertical beamwidth of 30˚ typical, custom models with a vertical beamwidth from 10 to 30˚ are also available.
