ON4UN built such a wire 80m vertical 4-square around his full-size 160m
vertical. The 80m array was 20 meters on a side and used a single
elevated radial elevated under each element. It is described in detail
in his book, Low Band DXing (including the latest, 5th edition).

Hello,
Now that my 100 foot tower is installed, I would like to assemble a ground
mounted 80M vertical 4-square array. Each of the 4 vertical elements would
be the full ¼ wavelength long and I would use 60 radials of ¼ wavelength
(in the air) length at the base of each vertical. Where the radials
overlap, I plan to solder the radials to a 2” wide copper strap.
My question is, what is the minimum distance from my tower can the closest
80M element be so the tower does not impact the gain, F/B, and directivity of
the 4 square? Is there a rule of thumb for this situation?
Just as members of this reflector helped me through the building my first
tower, I would really appreciate all the help you can give me on this
newproject.
