	RG58 is 50 ohms impedance.  That is what is generally used for
"Thinwire ethernet".  RG59 is 75 ohm cable and CANNOT be used for ethernet.
I understand some people may have gotten away with it bu their transcievers
must be extremely forgiving (most are not).  In any case, if it works at all
it is WAY out of spec.  IEEE spec is 50 ohms +- 1%.

>Can you mix them or should you use just one type?

	Don't mix.  Only use RG58.

An optimist believes we live in the best of all possible worlds.
A pessimist is sure of it!
