Abstract :
THE existence of two identical over-water radio links, one in the 250-and one in the 450-megacycle (mc) range, provided an opportunity for comparative studies of propagation in the two frequency bands. In making the studies, received signal strengths were recorded and shown as: 1. signal strength as a percentage of time, and 2. as signal strength probability. Observed signal strengths were compared to calculations made on the basis of previously published theoretical data.
