The horn antenna is a broadband passive device, shaped like a pyramid horn, referred to as a TEM antenna, which guides the beam of radio waves at a precise frequency. FT-RF Double Ridged Horn antennas have frequency capabilities ranging from 400MHz to 40GHz depending on type and style. These series are characterized by a huge frequency range and extremely high input powers. With increasing frequency, the gain rises to a maximum of 18 dBi. At higher frequencies, the increased gain compensates for the increasing cable losses.
The antenna main body with the bracket using CNC precision manufacturing, and adopt a more weather resistant material aluminum material and the surface through the 6061 and 7071 Aluminum special handling to prevent oxidation.
The horn is suitable for both transmitting and receiving purposes. the product is especially suitable for EMC and immunity test measurements.
Recommended Accessories
- Antenna Tripod: easy and fast-changing polarisation. 100% stable handling
- SMA Cable: High-quality special SMA cable

台灣本土疫情昨(3)日達到2萬3102例,疫情持續升溫。民進黨立委林俊憲昨晚在臉書指出,防疫下半場的關鍵就是第2劑與第3劑之間20%的差距,盼若無副作用的朋友能夠盡快接種。
林俊憲表示,疫情首度破2萬,但慶幸中重症率並沒有提高。另一方面,他說,第3劑疫苗接種率終於突破60%,第2劑也突破80%,而這中間的20%差距,將是防疫下半場的關鍵。
林俊憲指出,目前醫療量能緊繃的最主要原因,其實並非收治大量的病患,而是PCR篩檢癱瘓急診造成。他說,以各國經驗看來,疫情到這個階段,確診數已無太大意義,所有資源應該優先集中在中重症照護上,因此減少PCR對院所帶來的負擔是必然的方向,指揮中心也已開始進行。
林俊憲說,檢驗爆量等等的問題都可以透過行政手段解決,唯獨中重症率只能靠第3劑疫苗覆蓋率來壓低,這也是防疫下半場唯一重要的指標。他說,只打2劑未打第3劑的這20%朋友,或許各有各的原因,可是將是台灣能否安然度過疫情的關鍵,若非真的無法接受副作用,請趕快接種吧。
