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 up to full waveguide bands 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 110 GHz, but custom frequencies can be requested. The listed models are only offered with a waveguide or coaxial interface. While most models offer a fixed vertical beamwidth of 10˚ and 45˚ typical, custom models with a vertical beamwidth from 10 to 60˚ are also available for all waveguide bands from K to W band.
