[TowerTalk] resonant coax braid effect on ants?

Guys,

There has been plenty of discussion on
non-resonant guys and the desirability of having
them non-resonant lengths.

Now what about the outer braid of the coax you
feed your antenna with?
It's conductive, it is often run out from the
tower some distance below the antenna.  Can't it
be "resonant" and re-radiate too?  Why does this
not seem to be a concern.  

Another thing:

The RF you pump into your coax is supposed to
reside on the center conductor and the INSIDE of
the braid.  How is this possible when all UHF
connectors solder to the outside of the braid? 
Dumb question I know but it has been bugging me. 
I suppose I could go back to E&H field equations
and get an answer....
