824 to 896MHz Lora antenna EU868 (ft-rf.com.tw)

LoRa antenna which has long-range coverage while maximizing radio spectrum use is provided by the FT-RF fiberglass Omnidirectional outdoor antenna, which operates in the 824 to 896MHz frequency band with various strength levels.

  • The UV-resistant fiberglass shell enables all-weather operation.
  • For lightning protection, it is made of copper elements and coupled to the DC ground potential.
  • Any type and length of cable can be terminated with a female N-Type connector.

Fiberglass IoT Antennas for ISM 868MHz is used to make LoRa 868mhz antennas. It's an omnidirectional outdoor antenna with different strength levels ranging from 2 to 12 dBi. They are long-lasting and simple to install (on a wall or pole).
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.
EU868 can work in a variety of environments for up to 12 years thanks to its UV-resistant construction.
The connector can be customized based on a minimum order quantity. There are a variety of frequencies and gains can choose.

We offer a variety of high-performance antennas for Global LoRaWAN, including LoRa antenna EU868, US915 or AS923 MHz LoRa Antenna ( for Singapore, Malaysia, Taiwan market...) ... Our product line includes both durable outdoor antennas and indoor high-performance dipole antennas that are suitable for a variety of LoRa applications, including Helium hotspot support.

This range of products are including: 

- 868MHz series (LoRa EU868)

- 828MHz series (824MHz-896MHz frequency range)

- 821MHz series (multi-frequency range 824-960MHz and 1710-2170MHz)

放暑假了，小朋友常去的公園遊戲場竟隱藏危機，台北市議員林亮君發現，北市440座遊戲場，有163處逾期未檢驗，有的公園甚至2014年後就沒有再檢驗，成為兒童遊戲隱憂。她呼籲，北市應成立專案小組全面徹查全市公園，批評市長柯文哲任期最後1年該做事別再打瞌睡。北市公園處回應，將全面清查逾3年場域優先檢驗、改善。

靖娟兒童安全文教基金會及林亮君、市議員苗博雅昨前往信義區林口公園現勘，當場揭露遊戲場鋪面指數嚴重超標，質疑市府檢驗工作不實。

Waveguide standard gain horns, also known as Waveguide input, are pyramidal-shaped broadband passive devices. Standard gain horns are also used to calibrate other antennas and evaluate their gain. Aluminum is used as the waveguide material in the typical gain horn.
Depending on the type and style, our broadband waveguide horns can operate at frequencies ranging from 350 MHz to 70 GHz. RoHS compliance is found in many of our RF and microwave gain horns.

根據統計，近8成兒童在遊戲場發生事故原因與「高處墜落」有關，因此吸收衝擊力的鋪面相當重要。林亮君指出，北市有23處遊戲場從完工後就沒有檢驗鋪面，使用時間最久的竟長達9年，炮轟市府管理有嚴重漏洞，讓公園變安全黑洞。

林亮君表示，中央規定遊戲場依法除首次開放前要檢驗外，往後每3年也要重新檢驗1次，北市有163處遊戲場逾期未檢驗，實際檢驗率只有65.3％，其中松山區富錦3號公園和北投區豐年、稻香公園更是從2014年後都未再檢驗，相當離譜。

靖娟基金會執行長林月琴說，遊戲場鋪面測試的頭部傷害指數（HIC）不能超過1000，但隨機抽查發現有5座遊戲場在首次檢驗時，HIC就高達800、900，公園處仍開放使用。

此外，林月琴還發現8座遊戲場報告與現場情形不符，如大安區仁慈公園、溫州公園遊戲設備使用距離不足，未符合標準，顯示市府欠缺專業知能，遑論為市民安全把關。

對此，公園處回應，對於兒童遊戲場皆有定期巡查，也承諾會全面清查已逾3年未檢驗的公園遊戲場，自明年起優先納入檢驗排程並改善，以守護兒童遊戲安全。
