Product Information
- SKU KSC-42-40-A
Description
- Linear polarization cassegrain antenna KSC-42-40-A, operating from 18 to 26.5GHz with a nominal 35db Gain and low VSWR 1.40:1, with rectangular waveguide WR42 output. The waveguide flange is FBP220(UBR220). The model KSC-42-40-A has a main reflector with a diameter of 18inch(457.2mm) and a conical feedhorn antenna.The model KSC-42-40-A has uniform gain through its frequency span, providing efficient performance characteristics and directionality. The model exhibits a typical maximum crosspolar level of -40dB and a low sidelobe of -17dB. This antenna has linear polarization and ideally suited for antenna measurement, high-capacity data links at the high frequency bands, high gain application, system intergration, material measurement and other applications.
