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.

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。
