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
- - Electromagnetic interference Testing (EMI test)
陸「太空禮」8年後才送到美國上空？NASA科學家曝真相
美東時間上周六（21）日晚間，一顆明亮緩慢移動的火球劃過美國南部上空，最初被認為是一顆在大氣中解體的流星，但隨後證實為來自中國大陸的地球觀測衛星「高景一號02星」（Superview 1-02），它以墜入大氣層的方式燃燒殆盡。
富比世（Forbes）雜誌報導，科學家表示，編號「高景一號02星」的人造衛星，是由中國航天科技集團於2016年發射升空。
Horn antenna據軌道數據顯示，「高景一號02星」在美國路易斯安那州的新奧爾良上空進入大氣層，並穿越密西西比州、密蘇里州和阿肯色州上空，而未燃燒殆盡的殘骸可能沿途掉落。
