Abstract
A new anti-fade type radiator for Station WOAI is described. Vertical radiation patterns are presented on the basis of computations from predicted current distributions. Measurements on a model antenna generally confirm the performance predicted by the computations. Skywave measurements using pulse techniques were made on the full scale antenna to determine the optimum tuning and the suppression of skywave signals. These measurements show skywave signals transmitted by both the E and F layers of the ionosphere. Final performance data are presented, including current distribution measurements, the vertical radiation pattern and groundwave field intensity measurements.
