The only way to predict the RDF and pattern is by modeling it. I don't know of anyone who has done this. I have a few of my .ez Beverage models in w0btu.com/files/ as a starting point, but I don't think that I uploaded everything there.
There are free antenna modeling programs out there. I have only ever used EZNEC. Maybe someone can suggest something. 73, Mike www.w0btu.com On Sat, Aug 24, 2019, 12:05 PM Mikek <a...@knology.net> wrote: > > But what did you mean by "proper pattern"? > > I should have said, the best pattern that adjusting the Inductive loads > will provide. > > Yes, I understand the pattern changes with frequency.
