868MHz Antenna (EU868)
明天天氣如何?
週五(25)有兩個颱風生成，日本附近的是第15號颱風塔拉斯，結構型態差，也即將減弱轉往東北方移動，對台灣無影響，另外在菲律賓東方的是第16號颱風諾盧，未來將快速往西通過呂宋島，對台灣也沒有直接影響。週五(25)中午開始東北風已經明顯增強，但水氣量還不多，天候狀況仍跟週四(24)類似，南部有些午後陣雨，預計週五(25)晚上水氣將逐漸增多，迎風面的東北部將有局部短暫雨。
週末兩天東方有較不穩定的大氣環境、低壓帶外圍的水氣移入，配合偏強的東北風，迎風面的北部、東半部都有降雨機會，其中以北海岸到東北角、宜蘭、北花蓮沿岸降雨較明顯，有局部較大的雨勢機會，累積雨量也較多，天雨路滑外出須要留意行車安全，溫度也受到東北風及降雨的影響，全日是舒適到濕涼的感覺，中部山區、南部的午後對流也會略增多一些，平地大致仍穩定，但台南以北的沿海、平地區要留意強陣風。
預估下週一(26)水氣略減少，風向轉東北到偏東風環境，降雨的位置會漸漸轉到東半部地區，受到中層大氣的太平洋高壓影響，整體溫度將回升較多，西半部平地將有秋老虎的感覺，午後山區有熱對流發展帶來局部的短暫雨或雷雨，雖然預估雨量、降雨時間都不會太多，但天氣有些變化，到山區附近仍要留意天候狀況，晚間預估有輻射冷卻作用，局部空曠地區仍有機會降到二十初頭的溫度，日夜溫差大。

868 Mhz LoRa antennas are Omnidirectional outdoor antenna, which operates in the 824 to 896MHz frequency band and a center frequency of 868MHz - it's also known as EU868 (suitable for EU market)
- The UV-resistant fiberglass shell enables all-weather operation.
- Any type and length of cable can be terminated with an N-Type connector.
- Helium miner, Helium hotspot, RFID, WLAN, ISM BAND,868MHz Application
It's an omnidirectional outdoor antenna with different strength levels ranging from 2 to 12 dBi. The antennas are simple to install.

The OA-868M series, often known as EU868 (for the European market), is a license-free ISM band with a core frequency of 868MHz. The omnidirectional antenna employs an advanced collinear dipole design, which means it radiates uniformly in the azimuth with a high gain across long distances, reducing the number of cells or nodes required in a network.
