The EMCO model 3160-09 is a medium gain horn antenna designed for use in Immunity testing within the frequency range of 18-26GHz. They also have a role in shielding effectiveness testing when used as a pair (item390A). They are linearly polarised, with medium gain, half power beamwidth (equal in both horizontal and vertical planes) and a nominal VSWR over the recommended operating frequency range. They can be used easily with a fixed antenna factor over the range. The AF is 40.3dB and the gain is 16.8dBi. Both input to output are well matched to 50 Ohm & 377 Ohm respectively. Comparison of measured to computed gain & AF are generally well within half a dB and therefore can be considered as a standard for measurements within their operating bandwidth.
The 27 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 a “K”(f) connector. Mounting is with ¼ UNC receptacle on two brackets at 90 degrees. Power handling in its present configuration is limited to 50 Watts. If the end user can couple direct via the waveguide ( WR 42) then the horn can accept up to 10,000 Watts. See section 700 for coaxial connection. Items 748-753
