SAY-7138634212-110-X1

Rev. 1.1

Descriptions:
Model SAY-7138634212-110-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 0.110” circular waveguide with aUG-387/U-M flange. The antenna can support linear and circularpolarized waveforms and is designed and manufactured for indoor
and outdoor applications. By adding the mode transition, SAGE
Millimeter model SWT-12110-SB, the input port becomes a WR-12
rectangular waveguide that can only support linear polarizedwaveforms.
