I'm much more concerned as to how they are constructed and of what 
materials rather than where.  That said, If I can get US made of 
comparable quality (IE good Silver plated Brass) then I go for the US 
made.  Sometimes I have to settle for imports as they seem to be the 
only source for reasonably priced versus outrageous priced UHF 
connectors that fit LMR-600 and larger cables. We're talking $12 - $20 
Vs $80 to $125.

AT HF (160-10) the impedance of the UHF connector is of relatively 
little importance.  They are difficult to spot with a TDR and you can 
stack a bunch of them of good quality with almost no noticeable loss.   
The exception is on 160 where it's more a resistance problem, not one of 
impedance.  Even then I doubt it's of much concern unless running QRO 
which most of us on here do.

I had to use some imported UHF connectors on the LMR-600 run to the 160 
half sloper. I ended up modifying them by opening up the inside with an 
end mill for more clearance and higher voltage breakdown.  They looked 
the same after the mod as they did before.

I still check out the connectors at the swaps, but it's rare now days to 
find any good ones.  If some one is selling quality connectors I'd 
probably clean them out as I typically stock several hundred of various 
types.  I may have mentioned it before, but my work bench sets on three 
pedestals.  The top drawer on one is for coax connectors. One day I 
closed the drawer and it dropped right through the track and took the 
two drawers under it out as well.

I think I'm going to replace those pedestals with the large tool box 
bases on rollers. Even considering the price, if they hold up they'll be 
worth it.
