Weather radomes are mounted on the right wing of single-engine high wing aircraft such as the Cessna Caravan shown in your photos to present less of the pilot's sight blockage than if mounted on the nearer left wing. Cessna has offered such pod mount weather radar radomes as an option on some C210 Centurions, some C337 Skymasters and the C208 Caravans, among their prop or turboprop aircraft.
