The HS-034-UBR-10-NA is a high-performance Ka-Band Standard Gain Horn Antenna professionally engineered by Fei Teng Wireless Technology Co., Ltd. (FT-RF) for the WR-34 standard waveguide environments. Operating within the millimeter-wave spectrum across the continuous 22.0 GHz to 33.0 GHz frequency band, this premium antenna delivers a highly stable and precision-calibrated nominal gain profile of 10 dBi combined with an exceptionally low maximum V.S.W.R threshold of 1.3 : 1. Featuring a Direct Waveguide Input equipped with a standardized UG-1530/U (UBR Style) flange layout interface, it ensures optimal structural impedance coplanarity and ultra-low-loss power transfer, safely managing continuous wave power loads up to 500 Watts (CW). Precision CNC machined from high-grade structural aluminum alloy in Taiwan, the calculated internal horn geometry produces highly clean and symmetric 54° radiation envelopes across both horizontal and vertical planes. It stands as the definitive choice for millimeter-wave EMI/EMC testing architectures, advanced 5G system parameters validation, high-bandwidth satellite communication development, and mission-critical laboratory antenna characterization environments demanding uncompromised performance parameters.
