One thing I’ve learnt from this excercise it that “It’s a waste of time” getting the End Fed Half Wave Antenna as high as possible.
It works extremely well at arms height too. I hook the wire onto a branch / twig of a tree and tie down each end. In this picture the antenna was used to make contact with ZS5XT, easily 800km away (On 40m in the afternoon) using 5 Watts.
The antenna, at the “apex” was barely 2 meters above the ground!
During the “One contact per kilometer moved ” excercise, a distance of just under 1000 km was worked with relative ease under very similar conditions.
