Standard gain horn antennas are used as calibration devices that measure the gain of other antennas.
These antennas are made up of a combination of a Waveguide to Coax Adapter and Standard Gain Horn with Waveguide Input. It is a kind of simple combination but with great care and attention to create an antenna with accurate and suitable specs.
FT-RF Standard gain horn antenna product series includes waveguide sizes WR28, WR42, WR51, WR62, WR75, WR90, WR112, WR137, WR159, WR187, WR229, WR284 and WR340, WR430, WR510, WR650, WR770, WR975, WR1150, WR1500, WR1800, WR2100, WR2300, with broadband waveguide horn antennas have frequency capabilities ranging from 320Mhz to 40 GHz depending on type and style. with the gain of 10dBi, 15dBi, 20dBi and 25dBi.
Standard Gain Horn Antenna Applications:
Horn antenna太陽系可能不只八大行星？一顆潛藏於外太陽系、被稱為「第九行星」（Planet Nine）的神祕天體，長年來吸引全球天文學者投入研究。近期，由中興大學與清華大學組成的台日澳國際研究團隊，運用來自美日兩國的紅外線天文衛星資料，鎖定一組極具潛力的候選天體對，為尋找第九行星的存在，提供新線索。
上述研究成果已獲《澳洲天文學會期刊》（Publications of the Astronomical Society of Australia,PASA）接納發表。
研究團隊包含清華大學天文研究生藩玉龍（Terry Long Phan）與其指導教授後藤友嗣（Tomotsugu Goto）與中興大學物理系副教授橋本哲也，並集結日本宇宙航空研究開發機構（JAXA）、澳洲國立大學（ANU）等機構學者共同合作。
