SAY-7138634212-12-X1

Rev. 1.1

Descriptions:
Model SAY-7138634212-12-X1 is an E band Cassegrain antennathat offers a nominal gain of 42 dBi and a half power beamwidth of
1.2 degrees typically across the frequency range of 71 to 86 GHz.
The main reflector is fabricated with aluminum to offer a lightweight and rugged mechanical structure. The corrugated horn isused to provide the best feed efficiency and the most uniform
illumination. The input port is a WR-12 waveguide with a UG-387/U
flange. The antenna can support linear polarized waveforms and isdesigned and manufactured for indoor and outdoor applications. By
removing the mode transition, SAGE Millimeter model SWT-12110SB, the input port becomes a 0.110” diameter circular waveguidethat can support both linear and circular polarized waveforms.
