An amplifier is the best way to improve weak signal for your USB 309. 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. |
