PL-259's are excellent connectors when installed and used correctly. 
Unlike N and BNC connectors, a PL-259 is dependent on proper 
engagement of its outer shell and interconnecting teeth to the mating 
SO-239 socket. 


Use a small pair of pliers to snug up -- not tighten -- the shell. 
Be careful not to crush the shell by exuberant use of force! 
It takes just a few seconds to assure a reliable connection. 


When engaging the center pin, be suspicious if the mating force 
is unusually low.

Along the same line, use this thinking with your PL259/SO239 connectors. 
Sometimes even new ones don’t make a solid connection.
