If I have a 722K and an antenna connected to it will TV2 be able to pull in OTA locals? I know the 622 doesn't work but would the 722?
Yes, you need the OTA module installed in the 722k, about $30-40. You also need to be a dishnetwork customer with that box active on your account. The locals will show up in the guide after a off air scan is performed. The 622 has the OTA built in.
