Product Details
The HA-0218G-NF is a premium high-precision directional double-ridged broadband horn antenna engineered and manufactured by FT-RF in Taiwan for wideband microwave validation and high-fidelity testing. Operating continuously across the multi-octave 2 GHz to 18 GHz range (S, C, X, and Ku bands), this single-polarized radiator provides a gain profile from 5 dBi up to 17 dBi with symmetrical directivity. Precision CNC-machined from 6061 aluminum alloy with an integrated DC Short static protection circuit, it safely manages up to 300 W peak / 150 W CW, shielding downstream analyzers from surges. Equipped with a durable stainless steel N-Female connector, this lightweight 500 g antenna provides a stable average VSWR of 2.0 : 1. An indispensable reference for EMC/EMI pre-compliance, anechoic chamber field strength generation, and directional wireless communication monitoring.
