Hello Jimmie D:

Yeah there are after market and some antenna manufactures sell larger
diameter Gamma Matches to handle higher voltage in order to handle high
power output. The costly thing in the Gamma Matches is the use of a good
insulator like Teflon is real expensive.

I just put up a Moonraker 4 with some new and improved parts and pieces,
but still had the stock Gamma Matches. The Hubs, Mast to Boom mounting
plate, and and few other things had been updated, but I was disappointed
with the antennas performance. And I ran one of these antennas for a
long time.

Hi Jay, didnt know you could buy gamma matches. A guy gave me a Moonraker 4
beam a few years ago that had some damage . The gamma mctches had been
damaged so I replaced them with a piece of Al tubing and a piece of RGa that
had the shield stripped off.
