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