The Type 277 was a British naval sea search radar equipped with a PPI display. The RAF adapted it as the Type 52 radar for coastal defense. It had a full parabolic antenna that reduced sea return considerably and also gave it altitude finding capability. It could also be used for fighter direction and fire control.
