Below will be described simple one- length- wire HF antennas. The antennas were designed for mountain’s radio- expeditions. The main criteria were- low weight plus simplicity.  All described below HF- Antennas were tested in Northern Caucasus Mountains with a transceiver FT- 817 and ATU MFJ- 902 and provided good result.

 

... About Antenna Wire

 

Copper wire in the plastic insulation is the best choice. Diameter of the copper wire should be 1.5- 2- mm. Wire that is thinner – has no enough mechanical strength, wire that is thicker - heavy. Antenna wires should be not too hard but not too soft. It should have reasonable rigidity. Photo 1 shows some examples of good wires.

 

After choosing wires we should determinate the length for the antenna. In common the length depends on the used bands. 7- and 14- MHz bands are common used in the radio- expedition.
