Cleveland Runway 24R departure. While on takeoff and climbout; the First Officer's radar altimeter remained at 0 to -5 ft until reaching 3;700 feet MSL or approximately 2;500 feet AGL when it read correctly; then decluttered off our PFD. The Captain side radar altimeter read correctly the entire takeoff and departure. Departure Control was notified of the anomaly.Since ATC was notified; I planned on writing up my incident report at the hotel on the overnight from notes I had taken about the anomaly after takeoff. The radar altimeter operated normally into the next station. I have made an incident report regarding the radar altimeter suspected 5G anomaly.
Air Carrier Captain reported the First Officer's radio altimeter malfunctioned on climbout from CLE and cited 5G interference as possibly contributing to the event.
