Description & Specification
3.3GHz to 43.5GHz Open Boundary Quad-Ridged Horn Antenna
Dual Linear Polarization | 2.92mm (K-Female) | Model: HR-0343G-KF
The HR-0343G-KF is a high-precision Open Boundary Quad-Ridged Horn Antenna professionally engineered and manufactured by Fei Teng Wireless Technology Co., Ltd. (FT-RF) in Taiwan. Operating across the ultra-wideband spectrum from 3.3 GHz to 43.5 GHz, it provides stable directional gain from 2.5 to 12 dBi with a typical VSWR of 2.0. Featuring an optimized open boundary quad-ridged structure measuring 50 x 50 x 56 mm, it supports dual linear orthogonal polarization with excellent cross-polarization isolation. Constructed from precision CNC-machined aluminum alloy weighing approximately 150 g (136.96 g bare unit), it supports power handling up to 25W CW / 75W Peak and is fitted with high-frequency 2.92mm (K-Female) connectors. It serves as an essential measurement standard for radar testing, broadband spectrum monitoring, EMI/EMC compliance, and microwave laboratory validation.
