If you need to properly solder a UHF-Plug to a cable, you might consider

1. Properly applied, the crimp provides a gas-tight metal-to-metal seal.
2. Also, the ferrule provides a strain relief at least as good as the
braid-clamp in a conventional N or BNC connector.
3. For UHF connectors, double crimp = no heat and thus eliminates the
chance of melting the dielectr

Sam,
Crimped connections are superior to soldered whenever the crimp provides
a gas-tight connection.
In a similar manner, wire connections made onto square posts with a
proper wire-wrap tool provide a better connection than one which is
soldered.

I don't see any reason an OM or YL shouldn't put in N connectors instead
of SO-239's in a KAT100 if he or she wants to. The flanges are
interchangeable, or at least identically-drilled ones are available. If
everything else in the shack is N series, there's no reason to have an

They're fine connectors, but I don't see any advantage to using
them on your K2.
Their most useful feature is that they're constant impedance
50 ohm devices, as are the BNC's used on your K2. The PL-259
series is not 50 ohms. Trivia: There -ARE- 72 ohm Type "N"''s, but
they're not common..
