Abstract
This paper discusses the design and construction of a branch-fed, variable-phase, 20 to 55 Mc array of 48 log-periodic elements. Phasing to control-beam direction is described and the correction necessary for ionospheric refraction is presented in terms of vertical incidence critical frequency. The array gain as measured by moon-bounce techniques is found to be in good agreement with the theoretical value.
