Military Vehicle Antenna (Vehicular antennas)
三立準氣象/蔣季容報導
▲今日全台天氣晴朗。Antennas for Military vehicles or Vehicular antennas for heavy-duty use, such as in the forest or in remote locations on armored vehicles, and low-profile antennas for civil vehicles. Communication and EW applications are examples of applications.
Wideband mobile VHF antennas with frequency ranges of 30 to 88 MHz or 30 to 108 MHz are designed primarily for use in heavy-duty mobile applications.
Typically, the antenna is made up of three major parts: the antenna base, the lower part, and the upper part. Some antennas have two sections, while others have three. The long-lasting antenna base with GPS (optional).
The stainless steel spring absorbs shocks and vibrations while also protecting the antenna from collisions.
Both radiating pieces are comprised of composite materials, which allow for exceptional strength and roughness even in the harshest environments.
今(12)日全台各地高溫幾乎超過30度以上,僅北海岸及大台北東側有短暫飄雨。而周六(15日)鋒面雨帶通過台灣,白天雨勢明顯,不過晚上鋒面遠離,到了周日就恢復晴朗穩定的天氣。
三立氣象主播吳德榮表示,今日北海岸有回波產生,雲層不斷發展,稍微往南移動,下午北海岸及大台北東側有些飄雨,天氣稍微轉變。不過氣溫仍相當高,北台灣有30度以上,高雄也有33.5度,而花東也大約30度,全台屬於溫暖的天氣型態。
▲周六短暫變天,周日就恢復晴朗穩定的天氣型態。
吳德榮指出,明天天氣晴朗穩定,氣溫明顯回升,北台灣高溫來到30度以上,中南部甚至有34度。而這樣的穩定天氣將維持2天,周六上午鋒面雨帶通過台灣,中部以北雨勢明顯,南部則僅有山區稍有降雨跡象。
▲周六將有鋒面雨帶通過。
不過鋒面在周六晚上就會離開,吳德榮透露,周日恢復晴朗,北台灣高溫飆到32度,民眾要留意紫外線,外出做好防曬。至於南邊呂宋島熱帶性低氣壓已經減弱,吳德榮強調,目前確定不會發展,對台灣無威脅。
▲未來5日要留意日夜溫差大。
