Truck,
I've never run that amount of power into my Gamma Match, but I built a larger one that I believe would handle it.

Vector remake Post 25

I wouldn't allow Gamma Match deficiencies on any brand antenna be an ongoing issue as long as I can make one capable of doing the work. I have not had any moisture issues with my homebrew Gammas.
The first thing I'd try with the stock Gamma Match is to replace the tube with one of larger diameter. This tube diameter would be one that was suited to the thicker insulator tubing I'd use around the stock rod. I have used PEX tubing successfully for this insulator.
For the top of the Gamma Match tube I've done several things, but the best is perhaps the simplest. When I've gotten my match where I want it I simply wrap the top of the tube with electrical tape going on up onto the rod. When I'm satisfied with the tape job I use a good quality heat shrink tube over the electrical tape being sure the shrink is longer than the tape wrapping on both the rod and the gamma tube. Usually the shrink will not seal both those diameters effectively, so I have wrapped the electrical tape in a tapering fashion so that I can use a larger sized Heat shrink over the Gamma tube and the tape immediately above the tube, another smaller sized over the end of that heat shrink, and then yet a third smaller size over the upper end of that one. I have a completely sealed Gamma Match.
