Nothing new under the sun. I have been running my 80m
4 square 1/4 wl vertical array in 8 directions for
over 30 years.
It is really quite easy to do at least if you use
the W7EL Lewallen consept.
In the broadside directions you get slightly less
gain but you can still get good F/B.

Bob,
I found this by googling "4 square 8 directions":
https://ncjweb.com/bonus-content/k3lc4squarea.pdf
I think W8JI describes something similar on his website.

I really want to thank Jim, Jeff, Les, Mike, John and Gary for all of
their help, answers and ideas to which I have been giving a lot of
thought this week. The information gleaned has made me confident of
the new design. Unfortunately there is no way to avoid putting the
4-square elements around the tower so I know that interaction effects
will likely be noticed. Vicious storms have taken down all the other
tall trees that were previously in use to support my 80 meter 4-square.
Note to Jim Lux – I am particularly intrigued by your idea of changing
the feeding of the elements so that I can radiate broadside from the
side of the array rather than on the diagonal since the only trees
that I have to support elements happen to be roughly N, E, S and West,
which, with the Comtek phasing box, would give me radiation N, E, S
and West rather than the desired NE, SE, SW and NW.
The Comtek ACB-4 outdoor box uses the NW element in Pos 1 on the
outdoor , NE (2), SE (3) and SW in position 4 and arranged as shown in
the .pdf:
www.static.dxengineering.com/pdf/comtek_4_square_info.pdf
Which elements (N, E, S, W) would you put in which positions on the
box (so that the 4-square radiates toward the NE instead of East?
How is the gain and F/B and F/S compared to the standard pattern that
radiates diagonally?
Tnx to all & 73!

Hi,
I will be rebuilding several 4-squares this season as well as
restringing them in different trees due to Tornado damage (loss or
destruction of many trees at my qth) during Tropical Storm Isaias on
August 4th. I have a few questions for which I would appreciate your
guidance....
