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.

▲今日全台明顯降雨,明日天氣類似。
今(29)日農曆春節年假首日,受到東北季風、南方雲系影響,全台各地都有明顯降雨。對此,三立氣象主播黃家緯就表示,從今日起到年假結束前,總共有3波變天,最冷時間落在小年夜、除夕,北部有機會下探10度。
黃家緯表示,台灣今日天氣部份,濕涼轉乾冷,水氣一來還沒那麼冷,但接下來強冷空氣報到,這是第一波天氣變化,南投山區、基隆北海岸等迎風面一度發布豪雨特報,雨量累積超過百毫米,全台都有明顯降雨;而在氣溫部份,今日中午左右都還有19~21度,但到今晚就落在14、15度。黃家緯提醒,明日天氣與今日類似,氣溫還有可能下探。
黃家緯指出,明日西半部地區水氣逐漸減少,但在中南部山區、東半部、苗栗以北、基隆北海岸等迎風地區,降雨機率較高。

▲北部最冷時間落在小年夜、除夕。
未來一周氣溫方面,北部今日還有17度,明天小年夜就會下滑,最冷時間落在小年夜、除夕,小年夜14度,除夕就只剩下10、11度;中南部部分,最冷時間點一樣,中部11~13度、南部13~15度,中南部早晚偏冷,白天高溫有機會站上20度以上。

▲中南部早晚偏冷,同樣小年夜、除夕最冷。
黃家緯最後統整,小年夜、除夕受到冷氣團影響,由濕涼轉成乾冷,小心清晨低溫下探10度,白天陽光露臉,不會太冷;初一初二雲雨帶,水氣曾多,中部以北、東部、南部山區都有機會降雨;初三開始又會有另一波鋒面,初四馬上又有冷空氣報到,再度轉換成乾冷,等於年假每一兩天就會有變天感受,提醒民眾多多留意。
