In the rare situations where cellular coverage is less than great, or you’ve received a notification from your system indicating that your connection needs additional support, you may benefit from the optional extension antenna.
Simply unscrew the original antenna and attach the extension antenna in its place.
The extension antenna can then be placed closer to a window, or away from obstacles, in order to receive a better signal.
