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)

科學界普遍認為，地震帶上每數十年到數百年，就會釋放能量出現大地震，不過英國有最新研究推翻這個看法。該團隊透過研究喜馬拉雅山上的「拉拉湖」沉積物，發現大地震的發生不會依照特定週期，而是相當隨機。

Horn antenna喜馬拉雅山上的「拉拉湖」，每當發生規模6以上強震時，就會形成明顯的沉積層。而英國南極勘測團隊，在湖內一共挖出50層的沉積物，且透過碳定年法發現沉積物最早可追溯到6千年前。科學家在分析沉積物後，認為大地震的發生，並不會依照特定週期，而是相當隨機，有時候還成群出現，因此更難預測。

Horn antenna英國南極勘測地球物理學家蓋佐伊指出，我們以為再等個數百年或數千年就會發生大地震，但如今已不能仰賴這些數字，「我們分析這些地方的地震紀錄，發現地震並沒有遵循這些週期，不像時鐘一樣的規律」。
