It sounds like a nice combination, Len. I have something similar, with a
TH-11 at the bottom of my mast and a 40-2CD 12 feet above it. One of the
things to be careful about is that your mast is strong enough to carry the
load of that 40-2CD that far above the top of the tower. You will probably
need to go with a 1/4" wall steel tubing with a yield strength of at least
70,000 PSI. This assumes a standard 2" diameter mast.
In any case, welcome back to the wild and wacky world!! :)
73, Dick
