We've tried connecting thin and thick ether cables together with lots of
adaptors and not had any noticeable problems.  Using a TDR (Time-Domain
Reflectometer) to look at the mixed cable I saw some small impedence
lumps (discontinuities) but they are on the same order as those I see
where transceivers are tapped in, so it seems to me that there is little
or nothing to worry about.

We're using garden variety RG58/U cable with crimpon BNC connectors,
ordinary N to BNC adaptors, and N barrel fittings.  Nothing special.
