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 advantages of Horn antenna:
- Wide bandwidth: Because the horn antenna has no resonant parts, it can function over a wide range of frequencies.
- Easy waveguide interface: These antennas are very easy to interface to waveguide due to their shape, but they can also be designed with a transition so that a regular coaxial feeder can be used.
- Easy to make, simple design.
The application of horn antenna
- Antenna feeds for parabolic reflectors
- Radar systems with a short-range

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。
