Effects of security fences on VHF/UHF propagation

G. D. Gierhart; M. E. Johnson

Abstract: A method of estimating the basic transmission loss, Lb, for VHF/UHF links that have low or buried antennas surrounded by security fences is presented, Estimates of Lb obtained are compared with experimental data.

Keywords: VHF propagation; buried antennas; UHF propagation; knife-edge diffraction
