I've have owned a number of DX Engineering antennas and I had good results
with most of them. The 20m models are built fairly rugged, using a 3 inch
diameter boom and elements starting at 1 inch diameter, all made using 6061
aluminum. They are a simple design with insulated elements using a single
driven element with a hair pin match. The 20DX-5 has a 44 ft boom, 13 sq.
ft windload and weighs 141 pounds. I found the SWR to be a little high
(2:1) on their some of their antennas, however if you are willing to give up
a few dB's F/B ratio you can make minor changes to the first director and
driven element and have a nicer SWR curve. Are you having a problem with
your antenna?

Hello,
I thought Id try this again since I didnt get a lot of feedback on this
subject.
Does anyone have any experience with this 20m monoband antenna from DX
Engineering? If you do, Id appreciate hearing your experiences. Has
anyone rebuilt or re-modeled this antenna? Or, does anyone have a
manual for it so I can model it?
Thanks and 73..
