No idea i'm afraid, it wasn't one of those frequencies that stuck in the
brain.  Surely there must be some web references to it somewhere though?
Maybe 3.4Ghz or thereabouts?

It's not BNC, but a screw-on crimp terminal of a similar type.

My cable run's quite decent actually, about 10m at least.

The speedbox terminates it into RJ45, which is rather handy, since =
that's
what goes into my Cisco.
