I just figured out how to weld brass, so I'm building a VHF 1/4 wave vertical with some 1/8" brass rod bought at the hardware store.

I made a circle big enough for one of those VHF connectors with the threaded body, and welded 4 pieces to it act as the radials. I then filed down the end of a brass rod small enough to solder to the center conductor of the SO-239. I'm going to cover it in epoxy for strength and to keep the water out.

My question is: Will this be durable mounted outdoors? Is there a reason why brass isn't used much for antennas? What about epoxy? Am I asking for trouble here?
