An experimental investigation on the propagation of radio waves over bare ridges in the wavelength range 10 cm to 10 m

The variation in received field-strength has been investigated as a receiver was moved over the crest and into the shadow of a bare ridge which approximated in contour to a cylinder. The rate of attenuation in the shadow of the ridge was found to agree, using horizontally-polarized radiation, with the values calculated from the formulae of Domb and Pryce over the whole range of wavelengths used, 9.2 cm to 11.15 m.
