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)
加拿大天后席琳狄翁（Celine Dion）兩年前對外界公開罹患罕見疾病「僵硬人症候群」，導致肌肉痙攣，宣布暫退歌壇，因為身體狀況已不允許她繼續登台演唱。她睽違3年復出，在今年的2024巴黎奧運開幕典禮上，獻唱「愛的讚歌」感動無數觀眾，秀出招牌的激昂高音，功力依舊不減當年。

不過，如今卻驚爆天后其實並非唱現場，根據「解放報」報導，作曲家艾蒂安格羅表示：「我們看到的表演，確實是經過修正後的錄音。」另外一位音效工程師也指出，聽得出來是預錄後的成果，此外也有許多專家附和此說法，顯然天后當時只是預錄演出。 席琳狄翁罹病暫退後，在奧運開幕式上感動近35億觀眾。(美聯社)
