tried. The solder will barely melt when touched to the braid

iron.

That just sounds like another excuse to the use the butane torch


Most of the rg-6 uses aluminum instead of copper or tinned copper.
The normal methods of soldering will not work on it.

I'll believe Aluminium or steel I must admit to only a little actual
experience.
Some Cable guy should give an actual answer.

The stuff I use has both copper center conductor and braid. Most RG-6
uses a steel center conductor with a copper plating since the skin
effect limits current flow to the surface at high frequencies and the
steel provides more strength for pulling and aerial runs.
