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.
Hi Amerigo,
The transmission line you constucted should work just fine--don't go buying any more line, because the
difference will be insignificant.
And another point you should be aware of is that the 3dB improvement using the EDZ is only in the direction at
right angles to the antenna, because the broadside lobe of the EDZ is somewhat narrower than that of the 1/2
wave dipole, and as a result, the gain in all other directions is LESS than that of the 1/2 wave dipole.
