We want to hook up a SUN 3/50 workstation in a cubicle that is wired
for RG-59 coax and our thin ethernet is RG-58.  We therefore have a
impedance mismatch since one coax is 50 ohm and the other is 75 ohm.
Someone told us that if the distances were small we could ignore
the mismatch.

We've been unable to find a suitable impedance matching transformer.  
Does anyone know if we really can live with the impedance mismatch 
and if so for what length wire or know a place that sells impedance 
matching transformers?
