Dan,
    You are _extremely_ lucky.  The "f" type connector is a 75 ohm connector.
Coaxial ethernet (10 base-2) type connections are 50 ohm connections.  If you wire
a 50 ohm ethernet connection with 75 ohm cable it should _not_ work.  If you are
lucky it may function but not on a consistent basis.  I expect that you are
dropping packets like crazy.  Lest someone claim that I am crazy I can state that I
have had to trouble shoot networks where someone has used 75 ohm cable.  The
problem is very difficult to locate as the 2 cables look quite similar.  In you
case the section of your system which is 75 ohm may be short enough (in length)
that it manages to work but this is _not_ a recomended practice.
