Radio-Wave Propagation Measurements over Sea Water

Propagation loss was measured at three frequencies 30, 140, and 412 MHz over various sea-water paths out to 40 nautical miles between a moderately elevated shore-based receiving site and a floating transmitter platform essentially at the waters surface and subject to wave motion. The measured losses agreed well with theory, assuming a standard atmosphere for the test conditions. Certain anomalies and ocean-wave effects were noted. In general, meteorological conditions were relatively constant and normal for eastern Florida in summer.
