It isn't a one or the other proposition. Split the OTA feed to both the Dish receiver and your TV. That way you can still watch TV OTA even if the receiver is recording on all the OTA tuners.
OOOOO, I like it! Any GOOD splitter will do I assume? I've got to get a better indoor antenna anyway, so
I'll do it all at once. All of my locals (Madison, WI) are UHF, so I'm looking for a good one.
