Description
Dual circular polarization corrugated conical horn antenna LB-CH-75-15-D16-A, operating from 11 to 14GHz with a nominal 15dB gain and low VSWR 1.40:1 with retangular waveguide WR75 output. The waveguide flange is FBP120(UBR120). The model LB-CH-75-15-D16-A has uniform gain through its frequency span, providing a nearly circularly symmetric copolar radiation pattern in a wide bandwidth and very low crosspolarisation. This horn antenna has dual circular polarization and ideally suited for antenna far field testing, reflector feed, CATR, RCS measurement and other applications.
