Description & Specification
8GHz to 20GHz Open Boundary Quad-Ridged Broadband Horn 1.85mm-Female Antenna
Dual Linear Polarization | 1.85mm V-Female | Model: HR-0820GB-VF (Upgrade version of HR-0570GB-VF)
The HR-0820GB-VF (Upgrade version of HR-0570GB-VF) is an Open Boundary Quad-Ridged Broadband Waveguide Horn Antenna professionally engineered and manufactured by Fei Teng Wireless Technology Co., Ltd. (FT-RF) in Taiwan. Operating across the microwave frequency band of 8 GHz to 20 GHz, it provides high-performance dual-linearly polarized capability with high cross-polarization isolation and low VSWR across wide operational bandwidths. Featuring an open boundary quad-ridged construction with an aperture profile measuring 56.21 x 56.21 mm and an overall length of 61.41 mm, it is precision CNC machined from durable aluminum alloy with an estimated net assembly weight of approximately 66.26 g. Fitted with two precision 1.85mm Female (V-Female) coaxial connectors and an integrated L-type mounting bracket featuring M2.5 threaded holes, it serves as an essential measurement standard for anechoic chamber testing, dual-polarized EMC/EMI measurements, and broadband RF monitoring.
