Time to get creative if you have the room. Try paralleling a 1/4 wave or
other lengths to force the feed point impedance down. Even run at right
angles to fill in the pattern. The Johnson will directly load a very wide
range of loads; Ive done strange ones with my Viking I (basically the same
rig, different final).
There is also a free version of Eznec if you want to play on the PC first.
