Horn Antennas

COTS. Custom Designed. High-Gain. Wide-Band.

A wide range of COTS and custom designed, standard gain and high gain wide-band horn antennas, 170 MHz to 500 GHz, with typical gain values from 10 to 20 dBi. Higher gain horn antennas are also available typically >22 dBi.

A variety of COTS and custom designed wide-band-octave and multi-octave dual polar and single polar horn antennas are provided including pyramidal, rectangular, conical, corrugated, multi-mode, sectoral, double / quad ridged, and dual polarised.

Horn antennas can be adapted to meet customer specific requirements, for example, waveguide-flanged and high power transition versions are available.

Applications include EW, SIGINT, Test & Measurement including EMC immunity and HiRF testing.

As with other Steatite products, bespoke designs or modifications may be accommodated.

Typical specifications – (DL = Dual Linearly Polarised & SL=Single Linearly Polarised)
