this type of antenna, called a "valley-span" antenna, functions as a capacitively top-loaded electrically short monopole antenna. the vertical cables are the main radiating elements, and the horizontal cables serve to add capacitance to the top of the antenna, to increase the power radiated. the antenna is divided into 2 sections of 5 elements, each fed with its own transmission line. these normally operate together as one antenna, but can operate separately so one section can be shut down for maintenance without interrupting transmission. the floor of the valley under the antenna is covered with an elaborate network of buried cables that serve as the ground system for the transmitter.
