Measurements of the radiation patterns of full-scale simple VHF antennas Half-wavelength dipoles were performed while the antennas were situated in a second-growth tropical forest in Thailand. The data was processed statistically using a digital computer to provide contour plots of the median signal strength as a function of azimuth and elevation angle. In addition to the contour plots of the radiation patterns for the two polarizations, estimators of the standard deviations of the signal strength, and a comparison of the relative gains of the average signal strength at the measured pattern maxima are provided.
