Abstract
A single data signal is transmitted by two transmitters to two radio zones having an overlapping zone therebetween. The data signal is frequency or phase modulated and is mixed in the transmitters with RF carrier waves of equal frequency. The data signal to one of the transmitters is delayed between 5.degree. and 50.degree. with respect to the original data signal to provide a phase difference between the transmitted signals.
