Thanks for all the replies everyone, very helpful as usual.  the links that
Oz posted seem to match up with the connector on my 5817a.
http://www.amphenolrf.com/media/wysiwyg/SMC_4.jpg  Its the male side of a
SMC connector.

I'll remove the broken one from the unit... take a few more pictures.  All
the comments on bypassing the power input option were very helpful
too.  i.e. the 05Q option.  I figured that should be pretty easy where they
sold this unit without the external power option.

Again, thanks for the detailed responses gents!
