Thanks for the info... dipoles are not my area of expertise... I can certainly see where the spacing could be an issue. I guess I wasn't thinking. Would probably make a pattern like a fur-ball now that I think about it. I do phased verticals in meduim wave, AM broadcast = long wavelengths. So I am kind of out of my element here. Do you maybe have any suggestions for Warren? Certainly someone with more knowledge will speak up now that he has better quantified the question....
