Got to agree i only use Amphenol connectors, expensive in the UK but well worth
the extra money.
But i get mine when i am visiting Dayton, so a lot cheaper

Junk connectors have several issues. One of the issues is control of
dimensions -- the diameter of the tip must be "right" to make a solid
and reliable connection to the mating connector. I've seen junk barrels,
tees, and elbows that had a tiny spring between the ends of the connector.
When I got back on the air in 2003, I stocked my "junk box" with a lot
of these cheap connector adapters at ham flea markets, and over the next
3-5 years, they caused outright failures and intermittent problems that
were difficult to track down. At one point, I had added elbow connectors
in my shack to make cable routing cleaner. An hour into a contest
running legal limit, I saw SWR going sky high on an antenna, found the
elbow very hot to the touch. Removing it solved the problem. The tiny
spring had overheated. I've had these junk connectors fall apart
mechanically. I've had the dielectric in junk PL-259s melt when I
soldered the center conductor. And so on.
W3LPL advises to use Amphenol connectors exclusively, and to use only
83-1SP for PL-259s. I strongly agree with him. I know nothing about
what's available in EU -- my comments apply to North America.
