Simple Ways to Increase Communication Range of a Hand- Held Radio

In the mountains I have used instead a counterpoise a knife in length 300- mm. I got increasing in the level from 54 to 56.

For good operation it should be used a resonance counterpoise. The length for the counterpoise should be 480- 510-mm depending on used diameter of the wire. Counterpoise should be placed at 90 degree to antenna. Use only rigid wire. Counterpoise from a soft wire does not work properly.

Note: With a counterpoise the radio antenna has directivity. Therefore after connection a counterpoise to the radio you should turn the radio to find maximum of the reception.

Picture shows antenna "ALAN" (470- mm in length), counterpoise with "crocodile," hand- held radio, two- band counterpoise for 145/435- MGz for two- band hand- held.

The same experimenters were made with hand- held VX-3, VX- 800 and C- 568. The experimenters prove above writing.
