Standard Gain Horn Antenna
- Select
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

手機充完電「不拔充電器」 你中鏢了？充電小心2惡習 太危險了
你出門前，是否習慣拔掉插座上的手機充電器？近日，中國大陸發生一場火災，將房間燒得一片狼藉，而罪魁禍首正是充電器。手機大廠高層提醒，消費者應注意以下兩點：使用原廠充電器和充電線，以及保持手機充電時的良好散熱環境。
據快科技報導，近期網路上流傳一段影片，顯示一間房間被大火燒毀，起火點正是充電器。另有一名女子在使用充電器為手機充電時，充電線也發生自燃現象。
實驗結果顯示，在未使用的充電器上進行電流測試時，仍有電流讀數。這是因為充電器是一種變壓和整流器，插上電源後便會持續工作。
