I have two DX Engineering 20DX-6 antennas. Both of them are mounted in the
clear, over a wavelength high and have the same poor SWR pattern. They were
built using the recommended settings and the lowest SWR is around 14.350MHz.
The worst spot is 14.150MHz where it's 2.1:1 and then it drops a little
going into the CW part of the band. I know I have to lengthen the DE (maybe
a few inches) and possibly the 1st Dir. Does anyone have any experience
with this antenna and already know what adjustments to make to bring the
resonance lower in the band? This information could save me a lot of trips
up and down the tower.
