Radio Waves introduced the Discriminator, a one-foot diameter antenna that operates in the 23 GHz band. The antenna has first side lobes 23 dB down from the main beam, which “greatly reduces interference” from other microwave transmitters when co-location is required, the company said. The antenna also meets FCC Category A requirements. Typically, operators in the U.S. need to utilize a two-foot antenna to meet category A in the 23 GHz band, Radio Waves said, adding that the lower profile reduces costs and improves aesthetics.
