Cale doesn't weld the 10K coils to the shaft.
The only real problem I have ever had with his antennas is the set screw that holds the whip in can become stuck and required heat to get it out without destroying the threads.
I did some on the air testing years ago with a 22 inch shaft, a 27 inch shaft , both single coils, and a 96 inch fiberglass whip.
There was not that much difference.
And this was done mobile to base, @100 miles plus and on 10, 11, and 12 meters.
