N-connectors at full legal limit: I exclusively used N-connectors when
doing EME at 1.5 kW on 2-Meters. No problem. A short run of RG-8 coax to
the Bird meter got warmer than the connectors in that application on 144
MHz. N-connectors have no problem taking full legal limit on HF.

It's interesting how the focus or center of discussions drifts. This
started about testing filters with UHF connectors, so obviously they would
have to be used in this case.. The discussion of N connectors has happened
often, and in fact I'd read some time ago that, as well as 'inertia', one
strong reason for using UHF connectors on ham gear was power handling.
Someone in that discussion said that N connectors wouldn't handle ( or
maybe just wouldn't be reliable) for high-power ham rigs. The main reason
given was the small center pin of the N connector. (I suppose if that's
the case, BNC's might have the same problem.)
It would be good to know how much improvement was gained by the folks who
have changed their HF station connectors from UHF to the N series, both in
transmitting and in reception measurements.
Somewhat related to this (but not the NanoVNA) has anyone researched the
development of the UHF (SO-239/PL-259) series and what it's original
purpose might have been?
