單極化喇叭天線

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 s have frequency capabilities ranging from 400MHz to 40GHz depending on type and style.

FT-RF can adjust the connector and increase the waterproof mechanism and can be combined with multiple antennas.

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.

FT-RF antennas are designing and manufacturing in Taiwan with an RF network analyzer and adjust the testing laboratory to ensure the stability and quality of our products.

With more than 15 years of experience in researching, developing, and manufacturing this line product. FT-RF Antennas are lightweight, easy to install, and design for a quick test, with an average gain and factor design and VSWR. They are suitable for RF chamber, antenna calibration, RF component testing, interference antenna, signal collection antenna, and characteristics of various RF designs. In addition, they have high power, low F/B, durability, and a three-year warranty.1mhz to 70ghz any type antenna

戴口罩戴到長瘤，聽起來很可怕！高雄有一名七歲女童，因為戴口罩時耳帶都會打結，好讓口罩更密合，但反而長期壓迫耳朵，造成軟骨發炎，竟然形成一個一公分大小的腫瘤。還好在醫師治療之下，腫瘤已經逐漸變小，也呼籲家長應該讓兒童佩戴寬版耳帶的口罩，避免造成耳朵傷害。

女童左耳後側長了一個一公分大小的腫瘤，讓她每次摸耳朵就會痛，但導致腫瘤生成的原因，竟然是因為戴口罩。原來這名七歲女童都是戴成人口罩，口罩太大，家長就把耳帶打結，好讓口罩更緊貼臉部，沒想到適得其反，反而壓迫到耳朵，造成軟骨變形發炎，最後竟然長出腫瘤，另外還有小朋友同時戴了布口罩和醫療用口罩，兩層的耳帶也讓雙耳後側出現腫塊。還好經過醫師投藥治療，腫塊都已經變小。醫師表示，兒童的皮膚比較細緻，長期配戴不適合的口罩，就很容易產生疼痛，一旦發現有腫塊就要趕快治療，否則腫瘤變大，最後就只能動手術切除，呼籲家長可以使用口罩調節器，或帶寬版耳帶的口罩，避免小朋友耳朵受到傷害。
