The main reflector of this K/Ka band single circular antenna is a precision 28” diameter low-RMS lightweight composite with integral mounting hub. The primary radiator is a machined corrugated conical horn providing exceptional polarization discrimination performance, side lobe suppression, and beam symmetry. The primary radiator is capable of simultaneously transmitting and receiving using the same polarity. The Rx operating frequency range is 22.55 to 23.55 GHz. The Tx operating frequency range is 25.25 to 27.50 GHz. Each polarization operates over the full frequency band. The RF Input is a WR-42 flat flange with o-ring groove. The polarization is electronically switchable between LHCP and RHCP via remote control using a 24VDC switch.

Model: RPCS2.3-250-42O
