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.
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.

「梅花」颱風已於下午2時轉為中颱!氣象局表示,最快明週日(11)清晨至上午間發布海上颱風警報。氣象局局長鄭明典稍早也於臉書發文,「梅花颱風越靠越近、越長越大」。

梅花颱風強度漸增,下午2時升格為中度颱風,以每小時11公里速度向北北西進行。中央氣象局局長鄭明典在臉書發文,第12號颱風「梅花」,越靠越近、越長越大,現在已經是個中度颱風!還好颱風也沒有衝太快,給大家一個平安的中秋假期。
氣象局預報員陳伊秀表示,預估明週日,也就是中秋假期最後一天清晨至上午之間,就有可能發布海上颱風警報。至於有沒有陸警機率?得視其路徑是否再往西偏(更靠近台灣),七級風暴風半徑是否持續擴大到200公里才能定論。
下週一至週二(12~13日)「梅花」颱風會來到台灣東部外海附近,因為沒有明顯的導引氣流,速度變慢,近乎滯留,得等到14號星期三通過石垣島後腳程才會加快。不過其外圍雲系,預計從週日開始到下週四都會為台灣天氣帶來影響。北部及東半部地區有局部短暫陣雨,其中北部及東北部降雨較為明顯,山區及基隆北海岸有局部大雨發生的機率,其他地區仍為多雲到晴,午後有局部短暫雷陣雨。

「天氣風險WeatherRisk」粉專表示,受到梅花颱風外圍環流偏北風影響,明星期天到下週三(14日)之間,迎風面的台灣北部、東北部地區以及中部山區有陣雨,尤其北部、東北部山區有局部較大累積雨量,可能達到大雨或豪雨等級,提醒這些地區的朋友要多留意。
