Abstract : Results are reported of horizontally polarized signal strength measurements made at frequencies of 82, 210, 633, 1280, and 2950 mc. Height-gain runs were made at all frequencies behind 2 groves of liveoak and hackberry trees in full leaf. The sites were selected so that propagation took place over approximately the same path near the receiver terminal at all frequencies. Measurements were repeated at several distances behind the 2 groves of trees. Theoretical analyses are reported for several cases for comparison with field measured data. (Author)
