I would appreciate some input by all the antenna experts here on an article I just uploaded to one of my web sites. http://www.w0btu.com/files/antenna/vertical_stacking.html This is just a rough draft. Some wording needs to be changed, paragraphs need to be moved to a more logical order, and of course some graphics would help, but the thrust of my vertical stacking argument is there. Please let me know what you think, good or bad. I would like to publish this in a ham magazine, but whether that happens or not is another story.
