The EM model 7022 is the middle of a set of three octave horn antennas by EM Corp. designed for use in Immunity testing within the frequency range of 4 - 10GHz. Linearly polarised, with medium gain and a nominal VSWR over the recommended operating frequency range. They can be used with a fixed antenna factor over the range. AF: nominally 32dBs, with a gain of 14.5dBi.The 26 degree beamwidth in both polarisation planes is ideally suited to illuminate larger EUTs. These antennae have a detachable coax-to-waveguide feed, but come fitted ready to use with precision “N”.Mounting is with a 5/8unc skt. on a 90 degree swivel bracket.
