Abstract :
Propagation between these two buildings at a frequency of 177 megacycles has been studied with the object of providing a radio circuit with flat response over three megacycles. It was found that the received signal arrived over several paths, some of which were due to reflections from ground and from near-by buildings. The effects on the indirect rays of horizontal and vertical directivity, and change in angle of polarization were observed. The theoretical response curve for an assumed combination of rays was compared with the curves obtained experimentally.
