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.
