[TowerTalk] Soldering Ground Connections

[Keith Dutson]

Why would the heat at the connection be any more than at any other point in
the ground system.  Or are you assuming the impedance of the connection
would cause more heat at the joint?  Reason I ask is that if there is
tremendous heat developed during conduction, perhaps the ground system
conductor is too small.

This should never be done, period.  The reason is, think about it, during a
major energy surge event, tremendous heat may be present during large
current flows and any kind of soldering/brazing/etc will melt and you will
be left with no or a very bad connection.

You can do two things:

1.  Exothermic connection (CadWeld, etc)

2.  Mechanical connection (will require frequent maintenance since
mechanical connections will loosen on their own due to thermal cycling)

Do not solder or braze.  Phil  KB9CRY
