This adapter is for connecting 3G Dongles or mobile phones to a high gain antenna for improved range and communication. The adapter consists of a flat plastic sleeve with a 50 cm cable that terminates in a SMA Socket connector. The plastic sleeve (that looks similar to a phone battery) encloses a device that is able to couple to the dongle signal and divert it to a booster antenna thereby ensuring better dongle signal reception. The sleeve of the coupler is placed against the top of the dongle (see photos). (The coupler is supplied with a small piece of Velcro that you can use to ensure a more secure connection to your datacard). You then connect the other end of coupler to one of our booster antennas via the SMA connector. The booster antenna can be mounted on the outside of the building and pointed to your closest cellular base station to ensure good reception.
