That's why even with a 300-foot tower and hundreds of acres
of pasture with hundred foot trees I don't use LW arrays.

I think you mean -3dB BeamWidth and -30dB?? I don't follow

You might get a copy of Antennas and Transmission Lines by
John Kuecken. It was originally printed by Howard Sams and
reprinted now by MFJ. I used that book way back in the early
70's in college classes. It was based on a series of
lectures by John (Jack) Kuecken.

It has a chapter dealing with LW arrays, and my own
experiments have agreed. I've been generally unsuccessful in
finding a V beam (or even a Rhombic) that has substantially
more gain that a three element Yagi.

If  there is a V beam that does 20dBi and has a reasonable
beamwidth for that gain, I'm interested. I can do that with
a large distributed feed curtain array.
