Description

We offer a range of standard gain Horns from WG10 (WR284) to WG22 (WR28) in three values, 10dB, 15dB and 20dB. These horns are fully compatible to horns manufactured by Quasar Microwave and Mid Century Microwave when calibrating using the “2 antenna method”.

The physically larger sizes are predominantly fabricated in brass, and the smaller sizes electroformed in copper - to maintain the tight tolerances for these smaller waveguide sizes. Horns are manufactured with the full range of International Flange Styles as shown in the Flange Catalogue or with a variety of coaxial connectors on request. All our Horns are offered with an attractive hard wearing, epoxy paint finish.

Other gain values are available on request.
