Description
- Broadband Dual Polarization Horn Antenna LB-SJ-180500-1.85FSPO, operating from 18 to 50GHz with a nominal 15dB gain and low VSWR 1.5:1 with 1.85mm Female output connector. The model LB-SJ-180500-1.85FSPO has uniform gain through its frequency span, providing efficient performance characteristics and directionality. It can handle 5W continuously and 10W peak power. Constructed of high thermal and electrical conductivity durable copper, the horn comes with a specially designed weatherproof radome which provides excellent protection against the rain and dust but has very little loss across the full operating frequency band. This horn antenna has dual linear polarization and ideally suited for EMI testing, direction finding, surveillance, antenna gain and pattern measurements and other applications.
