Horn Antennas, Standard Gain Horns

The Waveguide Solution 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. WG16 through to WG 22 are generally electroformed in copper in order 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 TWS Flange Catalogue or with a variety of coaxial connectors on request. All TWS Horns are offered with an attractive hard wearing, epoxy paint finish.

Other gain values are available on request.

The Waveguide Solution facility is approved to ISO9001: 2008.
