SAF-4036031725-219-S1

AdvancedDescription:
Model SAF-4036031725-219-S1 is a WR-19 scalar
feed horn antenna that operates from 40 to 60 GHz.
At center frequency, the horn antenna exhibits 17dBi nominal gain and a typical half power
beamwidth of 25 degrees. The antenna has a returnloss of 20 dB, and -25 dB side lobe levels on the EPlane and H-Plane. The antenna is equipped with a0.219” diameter circular waveguide that supports
both linear and circular polarization. A rectangular waveguide port configuration that only supports
linear polarization is available under a different model number.
