To get the most out of your GSM repeater, it is important to find the best possible signal outdoors. In fact, there is nothing "magic" about a GSM amplifier: the GSM amplifier can "only" amplify existing waves and not recreate them from scratch. Also, the better the signal received, the better the performance of your GSM amplifier. It is your kit's outdoor antenna that comes "first," so it is important to do a careful installation. There is nothing complicated to do, you just need to pay attention to a few steps, which are described below.

Interference is the overlapping of two or more waves of the same frequency or otherwise very close together. If the interfering frequencies are close together, the GSM repeater may no longer work as it should. Take a look at this blog regarding suggested solutions on how to avoid interference.
