Title says it all, I am trying to use the RG-6 75 ohm cable I bought to make some matching stubs for a turnstile moxon rectangle pair for VHF/UHF. Right now I am just crimping to them but want a better solution. I bought a butane torch and tried to braze with some aluminum brazing rod... I think I need some special flux for that? I am not sure. What are your thoughts?
