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

俗話說「百善孝為先」,孝順這件是在華語社會中,擁有不可取代的地位,因此也衍生出不少民間俗語,好比「久病床前無孝子」這句話,就是講述父母病重臥床時間太久,再孝順、再好的子女都會有厭煩的時候,但是你知道嗎?原來這句俗語還有下一句,甚至更加悲哀。

「久病床前無孝子」後一句為「久貧家中無賢妻」,意思是一個家庭長時間貧困潦倒,這個家庭的妻子就不再賢慧,因為什麼事情都需要用錢,沒有錢的話還談什麼賢慧?此外,倘若經濟拮据,吃穿用度就顯得寒酸卑微遭人歧視,妻子肯定會感到心痛。這也透露現實生活中很多事都跟錢扯上關係,正好呼應「夫妻本是同林鳥,大難臨頭各自飛」,沒有麵包的愛情的確難以維持。

這2句警世俗語直截了當點出現實的人情世故,雖然非常殘酷,但如果從另一個角度思考,相信沒有一個子女會希望父母久病卻無法痊癒,妻子更不可能想要一直待在窮苦的家中,所以會挺身而出採取下一步行動,尤其現在也不是主張「男主外、女主內」的時代了,「妻子一定要賢慧」的觀念,早已慢慢有所改變了。
