On approach to 16R in SEA we experienced an intermittent RADALT failure. Weather was VMC; so a go around was not required. I first noticed this failure in the HUD at a RADALT of 390 AGL and approximately 580 MSL. It occurred one more time before touchdown. I am not sure if this is related to the 5G rollout; but though it was important to report. I made a logbook entry for Maintenance as well.
Captain reported experiencing radio altimeter anomalies on approach to SEA; citing 5G interference as the possible cause.
