While on a visual approach to Runway 09R; backed up with the ILS 09R-Z approach; we got a 'NAV RA 1 FAULT' message 2 nm west of KELEE intersection. Both radio altimeters appeared to be operating normally and displaying accurate information. The approach was continued to a manual landing without incident. Turn off 5G cell service near airports.
Air Carrier Pilot reported a malfunction with the radio altimeter while on initial approach to PHL.
