The 700MHz to 6GHz Double Ridged Broadband Horn Antenna is a highly versatile, precision-engineered radiator manufactured by Fei Teng Wireless Technology Co., Ltd. (FT-RF) in Taiwan for professional wideband microwave validation and wireless telecommunication infrastructures. Operating continuously across an expansive multi-octave range from 700 MHz to 6 GHz, it provides comprehensive, single-hardware coverage for 5G Sub-6GHz network characterization, UHF modules, and early microwave links. CNC-machined from premium structural 6061 Aluminum alloy panels with an integrated DC Short static discharge path, it delivers an exceptionally uniform gain profiling from 4 dBi up to 18 dBi while safeguarding connected high-value instrumentation from high-intensity transient electrical surges. Equipped with a premium stainless steel N-Female interface port, this industrial-grade 1450g radiator maintains a low average VSWR layout under 2.0 : 1. It stands as the definitive reference standard for laboratory EMI/EMC compliance sweeps, anechoic chamber testing arrays, and advanced directional signal monitoring systems.
