LORA omni antenna 

868MHz Antenna (EU868)

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.

[周刊王CTWANT] 身體有異樣,可能顯現在外表。中國浙江有一名大媽,日前帶著外孫去麵店用餐,被一名陌生男子狂盯著看,隨後對方告知「妳腦子裡可能長了腫瘤」,沒想到幾天後到醫院檢查,證實有顱內生長激素瘤。

根據《澎湃新聞》報導,該名陌生男子是諸暨市人民醫院神經外科主任趙明,當天在麵店吃麵時,發現大媽的面部有腦下垂體瘤患者的特徵,包括嘴唇肥厚、眉弓和顴骨突起、鼻子寬,雖然很冒昧,但出於職業習慣,她還是決定好心提醒,以免耽誤治療。

趙明先禮貌性幾句加常,接著詢問大媽是不是有糖尿病、近幾年容貌是否有變化,並觀察了她的手指,發現異常粗大,得到肯定回答後,他呼籲對方去醫院檢查:「妳腦子裡可能有腫瘤」,並表明自己是醫生,隨後留下聯絡電話。

大媽覺得很突然,但仔細想想,自己的相貌這幾年的確有明顯變化,以致於她有好幾年不願意拍照,半信半疑下到醫院諮詢,醫生也判斷有腦垂體腫瘤的可能,建議做進一步檢查。於是,她聯繫了趙明,經過核磁共振檢查,確診生長激素瘤,並進行切除手術,完整將顱內垂體瘤給切除。

趙明解釋,生長激素瘤是較常見的垂體瘤,雖然是良性的,但分泌過多的生長季會,會導致軟組織、骨和軟骨、內臟器官過度增長,主要表現為肢端肥大、皮膚粗厚、容貌改變等;腫瘤若壓迫周圍神經組織,可能出現視力下降、尿量增加等。

大媽後來順利康復出院,內分泌紊亂、手指肥大、鼻唇肥厚有所改善,但臉部骨隔變化已經無法改變,但是該慶幸腫瘤已經切除了。
