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)

大陸冷氣團發威，今（15）天清晨中部以北及宜蘭低溫普遍只有11至13度，且局部有輻射冷卻，空曠地區、內陸及花東縱谷會溫度再更低一些，尤其竹苗近山區出現10度以下，清晨最低溫在新竹關西，僅7度，新北市、新竹縣、苗栗縣、宜蘭縣也持續亮起低溫特報黃色燈號；不過，白天起大陸冷氣減弱將回升，冷熱交替，請注意氣溫劇烈變化。Horn antenna

Horn antenna氣象署說明，大陸冷氣減弱後，隨著太陽加熱氣溫迅速回升，北部、東半部高溫為20到23度，中南部則可來到25、26度，水氣上也減少，各地大多為晴到多雲、乾冷的天氣，僅宜蘭、臺東地區及恆春半島有零星降雨機率；風力方面，東北風仍明顯偏強，桃園至彰化、恆春半島沿海及各離島有平均風6級以上或陣風8級以上強風發生的機率，海邊活動請多加留意。

展望未來天氣，週三（17日）東北季風將再稍增強，北部及東北部氣溫稍下降，週五（19日）東北季風將減弱，不過，水氣反而稍增多，迎風面有雨，週日（21日）東北季風將再增強，北部及東北部天氣轉涼。
