The YG-118 is a broadband Yagi Antenna designed for use on ground-to-air communication circuits. It is vertically polarized and primarily used on longer VHF circuits since it provides 10 dB of gain. The antenna uses linear radiating elements which attaches to a rectangular support boom. Both the elements and the boom are made from aluminum. The antenna is of lightweight, rugged construction and is designed to withstand the environments normally encountered at airports.
