John,

Not sure if they have switched to crimp or not, but many of the bad reviews 
complain about poor solder to the braid. One of several jumpers bought from 
Universal Radio some years ago failed.  These were RG 213, silver teflon 
connectors soldered on.  Body started spinning on the cable.  Unsoldered the 
center pin and  it pulled right off.  The 4 solder holes in the body looked 
perfect, but  almost no solder  had gotten to the braid.

I suppose it doesn't matter whether it's crimp or solder, either done by a 
blind guy in the basement, or some engineers at M.I.T, it has to be the 
right connector on the right cable, installed the correct way, using the 
correct tools.  Otherwise trouble  will rear it's ugly head

That's why I avoid using the black coax seal and prefer  using silicon 
fusion tape followed by good quality  electrical tape.  That sticky stuff 
will keep the water out, but adds zero in strength or stability to the 
connection.   Also letting coax hang any distance  while only being 
supported by the  connector is  another failure waiting to happen  at 2 a.m 
in January.


73, Steve KW3A
