C / Ku band multi-polarization antenna feed OMT with frequency range selector
This antenna feed provides simultaneous reception of signals of two opposite circular or two orthogonal linear polarizations in the range of 3.4 - 4.8 GHz and two opposite circular or two orthogonal linear polarizations in the range of 10.7 - 12.75 GHz .
The outputs of the microwave converter units can be made connected to the WR-229 flange (accordingly to the range of 3.4 – 4.8 GHz (2 outputs)) and WR-75 (the range of 10.7 – 12.75 GHz (2 outputs)).
C / Ku band multi-polarization antenna feed OMT with frequency range selector is compatible with the antenna system, and the antenna feed must be coordinated in terms of the angles and levels of subreflector, the constructive solution of the device should ensure that antenna feed is installed in the focus of the antenna system!
