Standard Gain Horn Antenna
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)

中國河南省登封市嵩山玉皇溝景區有一塊「巨型蛇頭」彩繪石。(圖/翻攝自微博)中國河南省登封市嵩山玉皇溝景區有一塊「巨型蛇頭」彩繪石,雖然十分吸睛、驚人,但也因為太過逼真,嚇壞不少遊客,甚至因此被投訴。目前,景區已先用一塊綠布遮蓋。
根據綜合中國媒體報導,這塊巨石原本是河道內的天然原石,景區為增加趣味,於是邀請專人將其彩繪成「黃金蟒蛇頭」造型,與巨石天然輪廓相呼應,栩栩如生。
而從上傳於網路影片顯示,在湍流中,這塊被彩繪的巨石,如同蛇頭從水中探出頭來。當地管委會曾稱,彩繪是基於岩石天然形似蛇頭而設計,無安全隱患,遊客可放心遊玩。
目前「巨型蛇頭」彩繪石已先被塊綠布遮蓋。(圖/翻攝自微博)不過,這塊「蛇頭巨石」曝光後,遊客看法卻相當兩極,有人直言「這個蛇頭太嚇人,應該被覆蓋」,也有人認為「這是天然與創意的結合,應該保留下來。」
對此,景區一名工作人員表示,「我們不久前接到遊客投訴,於是安排工作人員對彩繪石頭進行了覆蓋。」後續將考慮重新進行其他風格的彩繪。
