868MHz Antenna (EU868)

The Twitter Blue Checkmark is seen in this photo illustration in Warsaw, Poland on 21 September, 2022. Twitter management has announced the introduction of a new verification label to replace the blue check previously given only to verified accounts. As the director of the service, Esther Crawford explains, unlike the blue symbol this one will be gray and it will be free.

As the director of the service, Esther Crawford explains, unlike the blue symbol this one will be gray and it will be free. Verified accounts will now have an 'Official' badge under their username, along with a gray verification tag. All previously verified accounts will receive the 'official' check mark which will not be available for purchase and not everyone will be eligible. (Photo by STR/NurPhoto)

雖然新版 Twitter Blue 還需要十來天的修改才能以「萬無一失」的狀態重新上線，但官方在 FAQ 頁面上已經透露了一些更動的方向。據悉未來新註冊的 Twitter 帳戶都需要等 90 天才能訂閱 Blue 服務，官方保留「在不通知情況下酌情」要求、調整等待期的權利，而此舉顯然是為了盡量避免藍標認證被冒名頂替者或其他惡意用戶濫用。除此之外，Elon Musk 還透露新版 Blue 在用戶改名後會暫時取消認證，直到官方確定其遵守服務條款後狀態才會恢復，Musk 認為這樣的安排可以給欺詐者製造更多的障礙。

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.
