Application Case
1. The GK-615 portable VHF radio has a short transmission antenna (about 20cm long), so the call coverage distance is limited, only 30-50km.
2. In order to enhance the coverage distance, it is necessary to remove the original antenna of the portable VHF radio station and replace it with a 10m long RF cable and an outdoor high-power antenna. The VHF antenna can be placed on the ground or erected on the roof of the machine room. As shown in the figure below.
3. The effective ground to air communication distance of the modified VHF radio is about 80-150km.
The VHF antenna is set up in the room.
