As I said earlier, I put the Qv4k up to right at 35' at the feed point. I removed the isolation from between the mast and the vertical antenna radial and put a ten foot metal mast pipe up into the bottom 13 3/4" of the antenna. The rest of my mast is wood. What I have is a nearly 9' (1/4 wave) length of mast in direct contact with the antenna from feedpoint downward. I experienced no significant SWR change from when it was 10' above earth and isolated from the mast. I continue to use a coax choke on the feedline.

SWR @ 10' and isolated:

28.755 ------- 1.5:1
28.305 ------- 1.4:1
27.855 ------- 1.2:1
27.555 ------- <1.1:1
27.405 ------- 1.0:1
27.205 ------- <1.1:1
26.965 ------- 1.2:1
26.515 ------- 1.8:1
26.065 ------- 2.2:1
25.615 ------- 2.6:1
25.165 ------- 2.8:1

SWR @ 35' and not isolated from a 19' section of mast:

28.755 ------- 1.5:1
28.305 ------- <1.4:1
27.855 ------- <1.2:1
27.555 ------- <1.1:1
27.405 ------- <1.1:1
27.205 ------- 1.1:1
26.965 ------- 1.3:1
26.515 ------- 1.8:1
26.065 ------- 2.4:1
25.615 ------- 2.8:1
25.165 ------- 3.0:1

I put the other 5/8 up on the roof this evening, but need some time to tune it in - SWR is high. Also, unlike I previously thought, it may prove challenging to get it to 35' where it is. I am at 25' right now, Perhaps by the weekend I'll be ready for some comparisons. As it is now, the Qv4k is eating its lunch in an unfair mismatched setup.
