Actually, nowhere in the post does he specifty stereo.
I'll cut him a break and assume he knows what he's asking for here. It may be for an antenna input. I've seen some stuff* that actually needs a mini plug for an RF input.
but, yes, if he really means stereo, then he's gonna need two RG6 cables and he's kinda up that proverbial narrow flowing body of water without a means of propulsion.
* a cheapo 8" LCD TV "valued at $500" we got for sitting through a time share talk. Yeah, $500 by whose value system?
