Even at 144 MHz, UHF connectors are probably acceptable, with the
bump being 1 cm in length compared to 200 cm. I think more at issue
is the environmental quality of the dielectric. The old military ones,
with what we used to call mud as the dielectric material are really
not very
insidebut I do think that the issue with standard mud type UHFs is
with the durability of the dielectric, not with the impedance bump, at
HF and even low VHF frequencies.
That's an accurate statement John. The largest bump I've even measured with
a SO239 PL259 pair was about 1.05:1 at

A long time ago, the USAF told me that N-connectors, when screwed down
