SAH-7531141060-110-S1

Rev. 1.0

Description:
Model SAH-7531141060-110-S1 is a W-bandchoke flange feed horn antenna that operates
from 75 to 110 GHz. The antenna offers a nominal
gain of 10 dBi, typical half power beamwidth in Eand H plane of 60 degrees and typical side lobelevels of -30 dB for both E and H plane. Theantenna port is a 0.110” diameter circular
waveguide with a UG-387/U-M anti-cocking flange that supports both linear and circular polarized
waveforms. A dual polarized configuration with an integrated orthomode transducer is available underthe model SAF-7531141060-110-S1-100-DP.
