Hi Frank,
Tnx for the input. Getting input to use copper strap from the radial plate to
the feedbox. The feedbox is where I have a relay to switch in a coil to go from
phone to CW. I already got the cables and ferrite made up so I guess it won’t
hurt to leave it that way. I want to keep the feedpoint off the ground because
of snow and ice. That is why I picked 3’.
With the elevated radial system I also switched in a coil. That gave me very
low dumped power with the Comtek box for both phone and CW.

Hi Tony,
Your proposed configuration will work fine. Your three foot wire
is actually part of your vertical. You're vertical will need to be
shortened a few feet to achieve resonance.
While its very important to use a common mode choke with
elevated radials, its completely unnecessary when you use radials
laid on the ground or slightly buried except in the case of a sparse
radial field which I'm sure will not be the case at N2TK,
Good luck, you'll like your results! Its well worth the effort.

Planning on changing from elevated radials to ground mounted radials for my
80 M 4-sq. After twice having to rebuild the elevated radials this past
winter from the snow/ice storms it is time to go to the ground. I plan on
having the feedpoints on 4x4 posts with the feedpoints 3’ up from the ground
so they don’t get snow covered often.
Looking at the DXEngineering Radial plates. It looks like an easy way to tie
the radials together on the ground then run a ground wire up to a box at the
feedpoint. Any comments or issues with using these radial plates?
Also going to use buried feedlines – RG6, ¾ wave with 8 turns through #31
big clamp-on core at the feedpoint.
