The QRFH-HA-6-FL from Cosmic Microwave Technology are Quad-Ridge Conical Flared Horn Antennas that have been designed to efficiently illuminate microwave reflector antennas over a frequency range from 0.5 to 18 GHz (FL to 6 FL where FL is 0.5 to 3 GHz). The feeds are dual-linear polarized designed for a given half-angle, HA, subtended by the reflector or sub-reflector facing the feed, specified for each feed. They are constructed entirely from Aluminum while the coaxial center line conductor and connectors have Gold-plated steel. These horn antennas have a return loss of more than 15 dB (over 90% of the band) and an aperture efficiency for half-angle of more than 55%. They are available in an enclosure that measures 34 x 40 cm with SMA connectors.
