Ionospheric Transequatorial Radio Wave Guidance at VHF.

Abstract

There has been a continuing interest in the use of the VHF band to provide communication channels which supplement those of the more conventional but congested HF band. The availability of these supplementary channels for large range transequatorial circuits was first reported by radio amateurs and studies of the phenomenon were largely experimental. The physical mechanisms involved in producing these channels have been and still are poorly understood. It is the purpose of this report to lay down the elements of a simple theory to explain the large signal strengths observed on these circuits and to describe the results of a computer model used to calculate them.
