I don't know the answer to that, but I was told that when the fire occurred, they didn't have a backup site and that they scrambled to build one on Chester Avenue. Until it was built, they fed the signal through a transmitter that had been used by another station.Unless this is the exact model of antenna as their old antenna what do they have to file with FCC? I didn't see a CP on the FCC site. I know with the AUX site they didn't have to file an STA.
