SAY-3834034706-219-S1

AdvancedDescription:
Model SAY-3834034706-219-S1 is a Cassegrain antenna that offers
a nominal gain of 47 dBi and a half power beamwidth of 6 degrees
typically across the frequency range of 38 to 40 GHz. The mainreflector is fabricated with fiber glass to offer a light weight andrugged mechanical structure. The corrugated horn is used toprovide the best feed efficiency and the most uniform illumination.
The input port is a 0.219” diameter circular waveguide with a UG383/U-M compatible flange. The antenna can support both linear
and circular polarized waveforms and is designed andmanufactured for indoor applications. By adding a mode transition,
SAGE Millimeter model number SWT-22219-SB, the input port becomes a standard WR-22 waveguide,
which can only support linear polarized waveforms.
