How to choose the gain of Rx and Tx ?
1、If there is a long RF CABLE (over 5 meters) or power divider between the extender and the hotspot, it is recommended to use the combination of RX = 17, TX = 6;
2、 If there is nothing else between the extender and the hotspot directly, it is recommended to use RX =10, TX =0.
