Broadband horn antenna LB-20180H-SFSPS, operating from 2 to 18GHz with a nominal 17dB gain and low VSWR 1.5:1 with SMA Female output connector. The model LB-20180H-SFSPS has uniform gain through its frequency span, providing efficient performance characteristics and directionality. It can handle 50W continuously and 100W peak power. Constructed of lightweight corrosion-resistant aluminum, the horn comes with a specially designed radome which provides excellent protection against the rain, dust and salt corrosion but has very little loss across the full operating frequency band. This broadband horn antenna is linearly polarized and ideally suited for EMI testing, direction finding, surveillance, antenna gain and pattern measurements and other applications.
