Due to my usual lack of patience, I presently purchase silver/Teflon PL-259
connectors, not for any potential performance benefit,
but that I can generally make a cleaner, and much faster solder connection to
the silver plug. If I'm not mistaken, one vendor even
allows you to purchase a PL-250 with a silver plug section, and a nickel shell
to keep per unit pricing low. I can generally use my
Weller controlled-tip 30-watt solder station with these. On the all nickel
PL-259s, nothing but my "big-bertha" 250-watt Weller gun
seems to work. But then, I run the risk of overheating the plug before
obtaining a good solder meld...only to find that the
phenolic insulator has become soft and distorted. Perhaps pre-fluxing on the
nickel would help.
