An amplifier is the best way to improve weak signal for your GT Max 3.6 Express. Amplifiers also require an antenna, which may need to be added separately if it is not a part of a kit. An amplifier will only boost the signal to the one device it is connected to - if you need to boost the signal to multiple devices, you will need a repeater. |
