Tony, Instead of a wire, consider using a short 1/2" wide copper strap from the radial plate up to the coaxial input connection on your box. I think you made the right choice in using a separate box for the feed. I recently did the same with NEMA 4x4x2 boxes mounted on a 2-inch pipe. The

I have a DX Engineering radial plate bolted to the tilt-over base of my aluminum tower.  It is very nice, and I use the coax cable feature to ground my feedline. It is really overkill for your purpose.  I would crimp *_and solder _*ring terminals onto each radial, with perhaps 1/4" holes.  I

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

Tony, I'm using a DX Engineering plate on my 160 inverted-L.  In my case, I also have the HD tiltover fixture mounted on a 3" diameter pipe cast in concrete.  I mount the plate a bit over 1" above the concrete surface so there is room to install the bolts around the edge of the plate from

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

Hi Tony, I had also looked at the DXE radial plate for verticals at my new qth. I settled instead on wide copper strap (a length of which you're probably already purchasing for the feedpoint connections) arranged in a square around the 4x4 and brazed the radials to that with a torch. This is

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
