Bill,
It really is better if a connector is installed as it's
designed to be installed. It may not be the easiest way of
doing it, but it's almost always the best way.
Having said that, I've found that using a propane torch
is the easiest way I've found to put on a PL-259. Takes a
little practice (and don't use MAP gas!), but not a problem
even in high winds. It helps to pre-tin any adaptors, etc.
