LORA omni antenna 

868MHz Antenna (EU868)

根據國外研究機構Pew Research Center資料指出，美國13至17歲青少年使用臉書的比例，已從2015年的71%下降到32%，而中老年人的比例卻超過58%，顯示老人比年輕人更愛用臉書！

青少年之所以不愛用臉書，其中原因固然是不想跟父母、長輩使用同樣社群，而「短影音」風潮興起也成為另一主因！包括抖音TikTok、YouTube Shorts、IG Reels，都推出15至90秒不等的短影音服務，讓年輕人玩得愛不釋手。

反觀臉書則因演算法經常更動、廣告太多等問題，讓國內網友備感困擾。Meta近來多次針對臉書的動態消息推出新功能，透過機器學習，讓用戶看到自己想看的客製化內容，且於社群與朋友進行互動。

該公司於周四（6日）宣布，即日起新增Facebook「動態消息偏好設定」功能，讓網友自訂動態消息顯示的內容，在官方推薦的內容或廣告上，點擊該則貼文右上角的三個圓點，便會出現「顯示更多」及「顯示較少」選項，點選後即可自訂動態消息的排序。

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.

其中，「顯示更多」將增加該篇貼文及相關內容的排名分數，反之，「顯示較少」會降低內容的排名分數；Facebook藉由這些網友的直接回饋，融入動態消息的排序中，讓AI變得更聰明。未來幾週也將於Reels短影音服務測試此項功能。

Meta強調，「動態消息偏好設定」功能會持續更新，讓網友自行選擇家人與朋友、社團、粉絲專頁與公眾人物發佈內容出現的頻率，透過動態消息偏好中的排名選項進行設定，包含「暫停追蹤」、「取消追蹤」、「重新追蹤」等功能；希望藉此讓用戶看到更多自己喜歡的貼文，並減少不喜歡主題的出現。
