I received many direct responses. Some suggested modeling the antenna, one
volunteered to model it for me, one suggested calling the manufacture (who's
out of business), one suggested a bad balun, and one said he put up the same
antenna and didn't have this problem. Thanks for all of these responses. I
now wonder if the problem could be from side mounting the antennas on my
tower. The tower is Rohn 65 (26" face) and the first director is only
inches away. Could the close proximity to this large tower cause some
detuning? I did have to readjust other antennas that were also side mounted
on this tower.

Subject: [TowerTalk] DX Engineering 20DX-6 SWR
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 around14.350MHz.
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.
