Antenna

An electromagnetic wave illuminates both an antenna and its feedline. Signal current induced on the outer surface of coaxial feedline may enter it at the antenna feedpoint. Common-mode signals induced on parallel transmission line may become differential at the receiver. Either makes the transmission line an unintended part of the antenna structure, which can degrade the directive pattern and forward gain. A current balun can attenuate unwanted coax shield current. A current or voltage balun can attenuate common-mode signals on parallel line. (consider using a Coiled-Coax Balun)
