My whole buried radial system uses this type of silver solder to connect the ground radials which are 1/2 in. copper tubing between ground rods. Each ground rod radial is also soldered to the Rohn tower base plate. It has been in over 20 years and no noticeable deterioration. I agree with the comment about using flux not incorporated into the silver solder.
Jim - KR9U _______________ With hard silver solder --the kind that melts at a red heat-- an oxyacetylene torch with a #4 or smaller tip works just fine. Just keep the flame size down, and/or turn down the oxygen a little for a carburizing flame*. This is similar to brazing, but brazing is much hotter and uses a silver-free brass alloy as a filler material. Use that opaque white borax-type silver solder flux, which is applied to the silver solder by heating the solder a little bit below its melting point, and then dipping the hot solder into the flux to coat it. Or, you can buy silver solder already coated; but IMO, it's not as good. I use MAPP gas and oxygen to silver solder nowadays, because it's all I have here right now. 73, Mike www.w0btu.com _________________ Topband Reflector Archives - http://www.contesting.com/_topband
