I want to combine the rf feed of tv2 (since it is stereo) AND ota feed into a single coax to be distributed to other tvs in the house. I presently am doing this with a 508 and a signal combiner that outputs the satellite programming on channel 4 (since I have a local on channel 3). Will my current signal combiner work or will I have to find something different? I have tried talking to technical help at Dish, Parts Express & others with some saying yes it will work & others saying it won't.
