Below is user's guide:
1. Need get 1pcs 6F22 9V battery for the power supply, peut't use switch power supply as there is EMI.
2. Once get battery and SM cable, antenna loop ready, the other end of the SM cable insert into radio external port interface or SDR receiver's input port.
3. Switch on and the LED light on means power on.
4. Switch the gain button DX/Local to find best effect position, clockwise gain bigger, counterclockwise gain smaller. Entre-temps, adjust the antenna ring's position too to get better signal.5. The antenna only for receiving signal, not for issuing.
