Radome

n. dome-shaped structure which houses a radar antenna

A radome (a portmanteau of radar and dome) is a structural, weatherproof enclosure used to protect an antenna. What distinguishes a radome structure from other structures is that the material used in building the radome allows a relatively unattenuated electromagnetic signal between the antenna inside the radome and outside equipment. Using conventional building materials (i.e. steel, aluminum, bricks, etc.) would block most if not all of the antenna signal. Radomes are used to protect the surfaces of the antenna from the effects of environmental exposure (e.g., wind, rain, sand, UV, ice, etc.) and/or conceal antenna electronic equipment from public view. They also protect personnel who work nearby from being accidentally struck by a fast-moving antenna.
