Here is my Eznec model with a full 1/4 wave radiator as 32' feet, 36' feet, and 36' feet with the mast isolated about 97" inches below the bottom hoop.

Bob you look to be right...this does reduce the currents flowing on the mast and the mast inside and right below the antenna. I isolated the mast with 6" inches, and I used 97" inches below the hoop...just a wild guess.

In the past I did not compare antennas when DX was working. And, I don't recall ever using my A/P during skip periods in the past. I was a bit surprised that I did not observe any advantage due to a horizontal beam...while I was contesting this past weekend.

I do remember years ago comparing an A99 and my Old Top One with a buddy about 5 miles away on his A99 and his 5 element horizontal Maco, but back then I saw a much better signal response from his beam when I was switched to my A/P. The A99 receive signal dropped noticeable when WJ was on his beam, and we saw the opposite both directions when I got on my A/P.

I know that DX signals typically vary noticeably, but I thought I still might see some difference, that is why I choose my New Top One to put up. I should have used my Marconi, and I will do that if we have another contest...and the Good Lord is willing.
