all I had was some #10 stranded wire. I made the spacers 1" apart and and
put about one per foot and the total feedling is approximately 25 ft.

it's going through an MFJ 941E Versatuner .
I can't get my SWR's below 2 . I'm sure there are a lot of varibles here

I was hoping someone could point me in the right direction.My first guess

that I should have used the #12 for the feedline and the #10 for the

Seems kind of strange the tuner would not match it..
The spacing probably has more effect on the feedline Z
than the wire diameter. Shouldn't really be that critical.
The wider the spacing, the higher the Z..
I guess you could try a different length of line..
Or scrounge up some other ladder line, maybe with a
different length. Even 300 TV line would be ok if it's
not wet.
Myself, I used to feed them with coax, and coax
series transformers. I imagine you could also feed
with coax and use twin matching coils at the feedpoint
for both sides of the element. Same as matching a
5/8 GP, you are just doing the same with a complete
antenna. I've never tried it, but it should work.

The way I understood it was the best way to feed it was with ladderline or
something equal to it. I looked at the wireman website and saw their 450 ohm
ladderline is only like 26 cents a foot so I'll order 80 feet of it and send
the antenna up higher and take it from there. The reason I built the EDZ is
it has 3 db over a dipole and it will also work for other bands with a
tuner.Another reason I made the EDZ is a real estate issue(lacking) so
something monsterous would be out of the question, but hey that's what makes
ameteur radio such a great hobby,the experimentation that goes along with
it.
