SAC-2507-219-S2

Rev. 1.2

Description:
Model SAC-2507-219-S2 is a Q-band conical horn antenna that
operates from 38.5 to 43 GHz. The antenna offers 25 dBi nominal
gain and a typical half power beamwidth of 9 degrees on the E-planeand 10 degrees on the H-plane. The horn also offers typical sidelobesof -18 dB on the E-plane and -28 dB on the H-plane. The conical horn
can support linear and circular polarization. The input of thisantenna is a 0.219” diameter circular waveguide with UG-383/U-M
anti-cocking flange.
