Abstract
Abstract A communication system for transmitting data between a transmitting platform and a receiving platform, having two equal lengths of leaky coaxial cable forming the transmitting antenna which is located on the transmitting platform and the receive antenna is located on the receiving platform. The two equal lengths of leaky coaxial cable form a circle wherein one end of each of the equal lengths is a feedpoint for inputting data and the other end of each of the two equal lengths is terminated with a resistor to ground. The receive antenna is maintained a predetermined distance from the plane of the transmitting antenna.
