- The folded unipole antenna is a type of monopole antenna; it consists of a vertical metal rod or mast mounted over and connected at its base to a conductive surface called a ground plane. The mast is surrounded by a "skirt" of vertical wires electrically attached at or near the top of the mast. The skirt wires are connected by a metal ring near the mast base, and the feed line is connected between the ring and the ground. It has seen much use for refurbishing medium wave (AM broadcast) station towers in the United States and other countries. When an AM station (mediumwave, long antennas) shares a tower with FM transmitters (VHF, short antennas), the folded-unipole is often a good choice. Since the base of the tower connects to the ground system, the transmission lines to any antennas mounted on the tower can run up the side of the tower without requiring isolation, even though the tower itself carries mediumwave current.
