Good morning. I have always been fascinated by various verticals appearing to "work" better when they are elevated. If it is really an HF vertical-vertical, then the highest one would want the feedpo
Hi Tom and all, One quick observation..... I have a 24' pipe, 1 1/2", mounted on a 4x4 post with about 40 radials. Each radial is about 40'. I also have a DX77 mounted on the top of a tower at 37'. O
Tom, I've not modeled verticals but have fooled with them for over 40 years in all kinds of configurations, from simple ground mounted verticals against a radial field to phased arrays. My favorite a
Tom, None of the responses to your thread described the vertical antenna characteristics in quite the same way as I have come to understand them, so I thought I'd throw mine in after the dust settled

Must agree with Tom's comments. Many years ago, DXers followed the notion that "higher is better" and included verticals in that thinking. directions". I believe the next significant improvement in v
Yeah, I know. I should have said "approaches 1" ... I was reading a graph which seemed to have a downward slope and was barely above the zero line at a base height of 1.0 wavelengths. The graph didn
I have not seen the aforementioned article... But, the broadcast industry did extensive experiments in the early days, as did Sevick, and a number of others in more recent years, including Al's excel

Although both books are cionsidered classics in ham circles, both contain dated material that has been superceded. Indeed, both should be classified as "vertical with ground plane" books, where gp i
