Topband: Radial plate

[N2TK, Tony]

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.
