I agree on powerpoles.  Anything I have that does 12V has powerpoles
on it now, and it makes life MUCH easier.  I rarely crimp them, I
prefer soldering.
Check the web page, they have a lot of different colors, and a
proposed standard for voltage/color.

BNC as an antenna mount has a major problem, in that the male center
conductor tends to spread and wear the female (boy this sounds
off-color.....) over time, since the BNC does not prevent the stress
from ending up there.   The SMA ends up rigid, but I have had the same
mystery disconnects.  Then again, I've replaced a number of female
BNCs in radios which were NOT all that easy.   A good design would put
the part that wears out on the antenna, which is easy to replace.
RPBNC would be a good choice actually.

FWIW, LDF1-50 or similar will work nicely in a male UHF connector if
you use the right adaptor sleeve. The andrew official UHF is
practically identical to a bog-standard UHF.
