Abstract : A system operating a 425 MHz was developed to measure propagation effects over an ocean path. The transmitter was installed on a boat and receiving antennas at heights of 6.4, 16.8, and 32 meters on a tower on Wallops Island. Data were taken during March 1983. The results are compared to theoretical curves of propagation loss generated from algorithms derived by Blake and Meeks. The experimental data falls between the two curves for 16.8 and 32 meters and follows Meeks' curve at the 6.4 meter height. (Author)
