The gamma I was using was the product of previous discussions regarding the Sigma/Vector antennas that were forwarded to me as a suggestion to get the antenna to match. I could achieve a low SWR with it, but I could not do so with the current length of the antenna, nor could I get anywhere near the match it is showing where I talk on the band as shown above - 27.387-- 1.0:1 -- R56 -- X0, and 27.564 -- 1.0:1 -- R54 -- x0.

The bandwidth seems more under control, too, perhaps indicating less potential loss.

I used this length for the radials on the original Qv4k, and the dog bone was 6" centered on that one.

I did change the bottom of the Gamma tube so that it directly connects to the feedpoint without any brass fittings.

I do expect the 85' coax feed into the shack to affect the readings on the MF259b. The manufacturers said it would lead to inaccuracies in the readings, but I checked them anyhow.
