The SAS-574 from A.H. Systems is a Horn Antenna that operates from 18 to 40 GHz. This linearly-polarized antenna provides a maximum radiated field of 100 V/m and has an antenna factor from 40.3 to 41.1. It can handle an input power of up to 10 W, provides a gain of 15 dBi and has a VSWR of less than 1.5:1. This double-ridge antenna is available in a housing that measures 4.1 x 1.1 x 1.4 inches with a 2.92 mm (female) connector, and comes with an attached tripod mount for horizontal/vertical mounting. The high gain, low VSWR, and input power handling capability make this antenna suitable for immunity and emissions testing.
