Description
Diagonal horn antenna LB-DG-5-25-A, operating from 140 to 220GHz with a nominal 25dB gain and low VSWR 1.2:1 with retangular waveguide WR5 output. The waveguide flange is UG-387/U-M. The model LB-DG-5-25-A has uniform gain through its frequency span, providing a symmetrical radiation pattern and extremely low side-lobes. It can handle high continuously and high peak power due to the waveguide interface. Constructed of high thermal and electrical conductivity durable copper, the antenna will provide years of trouble-free indoor and outdoor service. This diagonal horn antenna has linear polarization and ideally suited for illumination of anechoic chamber, antenna far field test, radar cross section (RCS) measurement and other applications.
