Now we are discussing some tricky stuff per say. Maybe tricky is not the right term for it.
force fed arrays, you can determine the pattern by shortening or lengthening the phasing lines (length of coax) used to phase the elements together and have a directional pattern.
ON4UN low band dxing book has a lot of info on this set up and google also has info.
N4JTE Vertical Array - Phased Verticals on 40 Meters!
Link describing how to construct a 40 meter vertical array just scale it down to whatever frequency you want to use.
I built one and they do work, do not know how it would work on higher HF frequencies.
