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.
今、明(24日、25日)兩天東北季風及華南雲雨區東移影響,中部以北及東北部天氣稍涼;台灣中部以北及東北部地區有短暫雨,並有局部較大雨勢發生的機率,其他地區及澎湖、金門、馬祖亦有局部短暫雨;恆春半島沿海空曠地區及澎湖仍有較強陣風。
中央氣象局指出,東北季風及華南雲雨區東移影響,今日基隆北海岸有局部大雨發生的機率,請民眾多加留意。
大雨特報:基隆市、新北市
中央氣象局長鄭明典在臉書貼出定量降雨預報圖,提醒:「今天白天的預測雨量!主要雨區在北部,室外活動請小心」。
氣象專家彭啟明表示,因為華南雲雨帶影響,周四、周五全台有雨,周六起水氣減少,逐漸轉乾、轉晴,不過北東部迎風面仍有陣雨,預計周日起回溫轉晴,下周三、四冷空氣南下,溫度約在15、16度左右,雖然目前看來還沒到達冷氣團標準,但和最近20度左右相比降溫有感,北東轉濕冷。
氣象專家吳德榮在「三立準氣象· 老大洩天機」指出,最新(23日20時)歐洲模式(ECMWF)模擬顯示,今日至周六(26日)清晨,鋒面持續影響,中部以北有局部雨,南部亦偶有局部短暫降雨的機率;降雨時大時小,間有空檔,應注意天氣變化。各地因雲多及微弱冷空氣,中部以北濕涼,南台氣溫略降。今日各地氣溫:北部19至24度,中部19至27度,南部21至30度,東部19至28度。
最新模式模擬顯示,投票日白天起鋒面減弱、降雨歇;西半部轉多雲時晴,東半部及大台北東側偶有局部短暫降雨的機率,影響輕微。周日(27日)至下周二(29日)白天,鋒面北移,各地轉為多雲時晴,氣溫回升,舒適微熱早晚涼。下周二晚東北季風南下,北、東轉雨,氣溫遽降。
下周三(30日)較強冷空氣南下,最新歐(ECMWF)、美(GFS)模式模擬顯示,台北氣象站約只能降至16、17度左右,離「大陸冷氣團」(台北氣象站≦14度)的標準,仍有一段不小的差距,但因為是入冬第1波,感受上還是會比較冷,要注意保暖。模式雖曾在誤差較大時(末期模擬),一度達標,但已連續數報調弱,包括最新的模擬;看來再調回「大陸冷氣團」的強度,機率很小!
