This is simply not true. The entire PL259 body and shell and the entire 
mating body are part of the connection. What IS correct is that 1) the 
connectors must be properly installed both to the coax and the 
equipment, and 2) that the shell must be well tightened, often described 
as "wrench tight," with the pins on the PL259 firmly seated in the 
notches in the mating connector. I'm being generic about mating 
connectors because it's equally true of SO239 and other connectors like 
barrels, elbows, tees, and inter-series adapters.
