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:

- Antenna measurement
- Radar Detection System
- Wireless Communication
- Spectrum Monitoring
- Electromagnetic interference Testing (EMI test)

Horn antenna許多人都有嘴饞時刻，但又怕吃進太多熱量。醫師許哲綸建議，此時不妨來些「毛豆」。因為毛豆富含植物蛋白、膳食纖維，及優質不飽和脂肪酸，每百公克就有14.6克蛋白質，熱量僅116大卡，且富含膳食纖維。營養師馬鳳吟也曾推薦毛豆，因其蛋白質含量超越雞蛋，且有助於排便、增加飽足感，能有效抗氧化，頗適合納入日常飲食清單中。

新陳代謝內分泌專科醫師許哲綸表示，毛豆是黃豆的「青兄弟」，富含植物蛋白、膳食纖維，以及優質不飽和脂肪酸。以每100公克的毛豆而言，熱量僅116大卡，卻含有14.6克蛋白質。「高蛋白與高纖維可讓人產生豐富的飽足感，最適合嘴饞、空虛的時刻。」

Horn antenna許哲綸並分享，基於料理方便，他家中常備有冷凍毛豆仁，最常料理的方法，就是灑點鹽，或淋日式醬油。在不解凍情況下，直接放入電鍋或微波爐解凍。

Horn antenna營養師馬鳳吟也曾在其臉書表示，屬於植物性蛋白質的毛豆有3大好處：

1、富含蛋白質：每100克就有13.8克，含量超越雞蛋，有植物之肉美譽。

2、富含膳食纖維：每100克有8.7克膳食纖維，有助於排便及增加飽足感。

3、抗氧化物多：有類黃酮化合物、皂苷及維生素C，能去除自由基，有效抗氧化。
