Single-Hop Propagation of Radio Waves to a Distance of 5,300 km.

Abstract

IT has been established that radio waves can be propagated between Ottawa in Canada and Slough in England by a single ionospheric reflexion. The one-hop mode of propagation is seen on the accompanying ionogram (Fig. 1) at frequencies between 27 and 33 Mc./s. This ionogram was recorded at 1800 G.M.T., September 11, 1957. The low-angle part of the one-hop mode is intercepted by the Earth. The high-angle portion is associated with reflexion at apparent heights of 600 to more than 900 km. The other traces correspond to two- and three-hop propagation.
