Ah, true.

No, I think frequency-wise, SMA is the superior connector.  The
difference it makes at 144MHz is probably "zero".  At 440, it is
probably still "very nearly zero".  If we were talking 1.2GHz or
2.4GHz it'd be a different story.

Practically: considering that 2m and 70cm gear is used "in the hand"
and probably swapping antennas a lot, BNC is better.

But you can't get 13 feet of high quality coax professionally mounted
to gold plated BNCs (free magnet with every offer) for $4.   :)
