I would like to hook my satellite box to my oppo udp-205 for two channel audio

What about cable rg59,,,, 2 /30 ft runs and adapters to rca male plugs

Regarding the possibility of ground loop hum that jea48 pointed out is true. But you (OP) could still go the coax option by inserting a ground loop isolator. Relatively inexpensive ($10?) and they do work. I use one that was provided/installed by my cable company.

First i would not use RG59, but better RG6 quad shielded.

Why 2 - 30 ft runs?

Does your SAT receiver box have a 75 ohm digital out RCA jack? If yes you will only need 1 digital cable.

There are several options you can use for the digital input on your oppo udp-205 player.

I know there are ground loop isolators that are made for CATV, cable TV, but I am not aware of one made for a Satellite Dish. I could be wrong though.

no digital out only rca red and white plus optical output
