Product Information
- SKU LB-20180-NFSPS
- Patents ZL201630458551.2 (China)
Description
- Broadband horn antenna LB-20180-NFSPS, operating from 2 to 18GHz with a nominal 12dB gain and low VSWR 1.5:1 with N Type Female output connector. The model LB-20180-NFSPS has uniform gain through its frequency span, providing efficient performance characteristics and directionality. It can handle 150W continuously and 300W 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.
