 Horrible mechaniclaly, but I am told the RF performance is not that bad.
 I've not tested it, though. 
 
 Many years ago, I worked in a calibration lab, and after (actually)
 ranting about how crappy a connector an "F" type was, I tested one to
 make a point....  and the damned thing was very clean.  Weird.  And,
 they're very easy to put together, relative to BNCs, for example.  That
 the electrical characteristics are almost identical to BNC connectors is
 something I still don't quite understand, although I believe the
 instruments...  (all HP equip.  <Grin>) 
Well, the inner diameter of the braid and the outer diameter of the
centre conductor stays *almost* the same right through the connector.
Mechanically it's as close as possible to a straight bit of wire.
