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)

捷運三鶯線預計今年中旬啟用，民眾憂被噪音干擾，新北捷運局宣布啟動「隔音牆優化」計畫，透過分區檢討與專業評估，首波將投入約6億元經費，針對學校及人口密集區優先施作，確保捷運便捷與鄰里環境能共生共榮。
新北捷運局長李政安表示，三鶯線整體進度已達95%，目前進入全線整合測試階段。為優化噪音環境，捷運局密集完成13場實地會勘，雖然目前監測值均低於法定標準與契約加嚴標準，但仍將針對重點路段對症下藥，採取主動與被動雙管齊下的減噪措施，以精準提升降噪效益。
在主動式減噪方面，李政安指出，2025年12月已完成全車隊車輪鏇削，解決測試初期因緊急煞車導致的異音問題，實測已降低超過10分貝，並同步調整夜間收車模式以減少干擾。被動式減噪則以「學區優先」，如北大國小、鳳鳴國中將新增2米隔音牆，三峽國中則加高2米，針對人口密集區也將依據環境量身打造優化方案。
捷運局強調，隔音牆優化遵循「分區處理、精準效益」原則，避免盲目設置全罩式隔音牆導致浪費公帑或影響高樓層景觀。第一階段工程僅能利用深夜收班後的3小時施工，力拚今年全線完成。未來完工後也將持續透過科學監測滾動調整，確保「錢花在刀口上」，帶給市民更舒適的交通與居住環境。
