Radome

A radome is a structural, weatherproof enclosure used to protect an antenna. The material used in building the radome allows a relatively unattenuated electromagnetic signal between the antenna inside the radome and outside equipment. Radomes are used to protect the surfaces of the antenna from the effects of environmental exposure.

Radomes can be constructed in several shapes depending upon the particular application using various construction materials (fiberglass, PTFE-coated fabric, etc.). When used on UAVs or other aircraft, in addition to such protection, the radome also streamlines the antenna system, thus reducing drag.

The word radome is a portmanteau of radar and dome.
