An Antenna Radome is a protective enclosure used by an antenna. It is made up of material that minimally attenuate the transmit and receive electromagnetic signals. Radomes are used to protect antennas in harsh environments.

Image 1: Example Radome. This is the protective covering for an antenna.

Image 2: Air-Filled Radome - In this Case, the Radome is filled with air.

Image 3: Radome used for mm-Wave Backhaul Applications. The Antenna and sometimes even the Tx/Rx modules are integrated into the radome.
