The radomes were typically at least 15 m (50 ft) in diameter and the radomes were attached to standardized radar tower buildings that housed the radar transmitter, receiver and antenna. Some of these radomes were very large. The CW-620 was a space frame rigid radome with a maximum diameter of 46 m (150 ft), and a height of 26 m (84 ft).
] AN/GPA-33 Radar Set Group for protecting a USAF radar's antenna and electronic cabinets. Designed for low temperatures and strong winds, the 25 ft high tower's top platform supported an antenna group and a 20 ft high CW-313/FPS radome (truncated sphere of 25 ft diameter, 450 lb) which was "capable of withstanding two inches of ice" and winds ...
It is to be installed on CVN-68, LPD-17, CG-47, WMSL-750, LHD-1, and LHA-6 ship classes. The system is X-band and the antenna consists of dual planar arrays mounted back-to-back under a radome. [2] Flight III Arleigh Burke-class destroyers are also planned to have the SPQ-9B. [3]
On top of this radar tower was a radar antenna 50 feet tall, 120 feet wide, weighing 85.5 tons, and rotating at 5 rpm. An available rigid radome 140 feet in diameter and 96 feet high protected this antenna from adverse weather conditions.
From 5% to 20% of rain fade or satellite signal attenuation may also be caused by rain, snow, or ice on the uplink or downlink antenna reflector, radome, or feed horn. Rain fade is not limited to satellite uplinks or downlinks, as it can also affect terrestrial point-to-point microwave links (those on the Earth's surface).
Use of the Eiffel Tower as a listening station to intercept wireless telegraphy (French: télégraphie sans fil T.S.F.) 1914 British radio listening station from the Second World War, equipped with the National HRO shortwave radio receivers The radomes of listening station RAF Menwith Hill, England, often referred to as "golf balls", protect the parabolic antennas from the weather.

[1]: 25–26 The radome material is designed so that the antennas can transmit and receive through the material. [1]: 25 The base of the mast is constructed from fiber reinforced composite skins encasing end-grain balsa core. [1]: 26 The upper (radome) section consists of structural foam and fiberglass. [1]: 26
