A wide range of COTS and custom designed, standard gain and high gain wide-band horn antennas, 170 MHz to 50 GHz, with typical gain values from 10 to 20 dBi. Higher gain horn antennas are also available typically >22 dBi.
Horn antennas are used in applications such as EW, SIGINT, test & measurement including EMC immunity and HiRF testing.
We can adapt existing or provide bespoke horn antennas to meet customer specific requirements, for example, waveguide-flanged and high-power transition.
Our COTS and customised horn antenna range incorporates wideband-octave and multi-octave dual polar and single polar horn antennas including pyramidal, rectangular, conical, corrugated, multi-mode, sectoral, single polarisation/double ridged, and dual polarisation/quad ridged. Our standard gain and high-gain wideband horn antennas range from 170 MHz to 50 GHz, with typical gain values from 10 to 20 dBi although we also design high gain antennas beyond this.
As with other Steatite products, bespoke designs or modifications may be accommodated.
