Radomes are used to protect the surfaces of the antenna from the effects of weather, including rain, sand, and ice.  When used as a covering for radar dish antennas, the radome also protects the sensitive antenna from debris and rotational irregularities due to wind.  When used on UAVs or other aircraft, in addition to such protection, the radome also streamlines the antenna system, thus reducing drag.  On stationary antennas, excessive amounts of ice and other similar weathering can actually de-tune the antenna to the point where its impedance at the input frequency rises dramatically causing its voltage standing wave ratio to increase and the reflected power comes back to the transmitter where it may cause significant overheating.  Thus, radomes are a critical and important part of the overall antenna system’s design and functioning.  Lew Aerospace’s radomes are specifically designed to maximize the performance and overall operational functioning of sophisticated communication and radar systems.
