Repost with correct topic, OE strkes again! Usually mechanical connections are used in antenna ground systems. Here is a summary of my experience on brazing: The joint should be clean and shiny. Coated brazing rods are nice but good flux is essential. A four ounce container of flux from a welding supply store costs about $6 around here. It will last very long time. It is corrosive so make sure you clean up well afterwards. You must have adequate heat, usually a propane torch is the minimum with acetylene preferred. Some use the a product called Mapp gas". Brazing is essentially a high temperature soldering process. The joint will need to get to a dull red to flow properly. The flux melts an shields the joint from oxidation. Silver solder is a little easies to work with, but good supplies are very expensive. There is a world of difference in dealing with silver bearing solder and the real stuff. The last time I priced top quality Harris Silver Solder it was about $80 for a four ounce roll! The higher your skill level, the better you can deal with minimal equipment and supplies, just like life in the electronics world.
