The adaptor consists of a flat plastic pad with a 50 cm cable that terminates in a SMA (female) connector. The plastic sleeve, that looks like a cell phone battery, encloses a device that can couple to a cell phone and divert it to a booster antenna thereby ensuring better reception. The pad of the coupler is placed against the top of the phone. (The coupler is supplied with a small piece of Velcro that you can use to ensure a more secure connection to your phone). You then connect the other end of the coupler to one of our booster antennas via the SMA (female) connector. The booster antenna can be mounted on the outside of a building and pointed in the direction of your closest cellular base station to ensure good reception.
