The LoRa 915MHz antenna is an omnidirectional outdoor antenna that operates in the 902 to 928MHz ISM band and has a core frequency of 915MHz. The antenna is intended for use in industrial and environmental monitoring, mesh network applications, and LoRa and LPWA networks, among other things. This series omnidirectional antenna radiates consistently in the azimuth from 3 to 9dBi gain. This collinear design feature gives the highest performance, providing better coverage and hence longer range in the horizontal plane over 360 degrees, reducing the number of mesh nodes required. Because of the UV protection, this design is extremely robust and can be used in any weather condition, even in a tough environment. Lora 915Mhz antennas are simple to use and may be immediately connected to access points. One pair of packing contains a U-bolt and waterproof tape, allowing the antenna to be mounted on a wall or pole depending on the situation.

就怕小朋友傳達不夠完整,聯絡簿是學校老師跟家長溝通的重要管道。日前有名家長抱怨,說他每年都會收到一張小孩學校發的回條,但他質疑校方發這張回條根本是想陷家長們於不義。
該名家長透過臉書社團「爆怨公社」發文抱怨,說身為兒童家長的他,每年都會收到「圈選班級家長代表」的回條,而該回條是由學校家長會發出,主要是想請爸媽們協助選出2名熱心家長,擔任班級的家長代表。
不過,原PO直言:「雖然不具名,但是家長間互相都不認識,要怎麼選賢與能?根本陷家長們於不義!」。

貼文一出,網友紛紛留言,「我是直接寫棄權」、「盲選…昨天收到當代表整個大傻眼」、「對我真的很迷惑,每次我都害怕極了」、「我連班導都不認識」、「當然選有錢的家長啊」、「這真的是很不妥的選舉方式」、「因為老公不知道圈誰,選擇空白,小孩子(被)罰不能下課」。
還有網友說,「通常都直接選1號 」 、「選1號+1,都不認識啊 」、「 我都投1號,反正誰也不認識,第一個號碼就你啦」;也因此釣出苦主表示「因為兒子是班上1號,常莫名當選」。
