BE CAREFUL!

The cable you called out "RG58/U" is rated at 53 ohm impedence.  It
WILL cause noise problems.  What you want is "RG58C/U" which is 50 ohm.

We use thick to thin cabling with N to BNC adapters with good success.  (We
even used the "wrong" RG58 until some of our HW types started looking closely
at the E'net interface!")
