The 625 cannot receive any OTA AT ALL because it does not have an OTA tuner - either analog OR digital. All the 625 can receive is DBS signals.
The ANTENNA port on the back is to enable OTA passthru only. Sort of like a VCR.
Edit - now - if you mean 622 - that has an ATSC digital OTA tuner that would need to be connected to an antenna.
