Billy, I have the same problem with my 130' tower being in the middle of
my 160M 4 square. I have a shunt wire dropped from the 60' point on the
tower to ground were I put a MFJ-931 and tune for zero current flow when
the 4 square has 2kw of RF into it. The same tune is used in any
direction of the 4 square. This method works very well.
