Abstract:

The report presents results from a special series of measurements designed to characterize the influence of a jungle environment on the transmission of digital signals. Measurements were conducted by transmitting a swept frequency signal, 4 MHz wide about the center frequencies of 50, 100 and 150 MHz, and photographically recording the received envelope and phase, compared to a fixed reference antenna at the receiving terminal. The test antenna was incrementally moved along both a radial and transverse direction with respect to the line of transmission from the transmitter.
