How to use the small whip antenna:
 
1. The knob above is the band switch of each frequency. The knob below is for fine adjustment of frequency and vibration point. The upper outer ring 11 and inner ring 50 represent the common position of 11 – 50MHz. 8 and FM represent 8MHz and FM bands can use this position. And so on. Then select the knob below to fine tune to find the best standing wave suggestion link talent to check the vibration point.
 
2. Expand the use method: remove the rod antenna. Connect a 20 meter long line. Long lines are erected high or on the roof. The tuning method is the same as above. The launch efficiency will be improved several times!
