Horn Antennas

Cobham provides end to end avionics and covert surveillance solutions

Physical Dimensions

Cobham Sensor Systems builds two distinct types of horn antennas: Standard Gain or Calibration Horns, and Broadband Horns.

Standard Gain Horns are optimized for low VSWR and provide equal E- and H- plane 3dB beamwidths. These horns are most often used as gain standards for antenna testing. VSWR data are typically supplied with each horn. Calibration data is also available upon request.

Broadband Horns are optimized for high efficiency, constant gain and constant impedance versus frequency over multi-octave bandwidths. These horns are used for EMI/RFI measurement and radiation, antenna gain and pattern measurement, reconnaissance/surveillance and other applications.
