Annotation

An approximate method is proposed for calculating the shape and the directivity pattern of a linear antenna placed in an undercurrent, as well as the dispersion of the directivity pattern due to the statistical scatter of the flow velocity. Methods for optimum selection of antenna parameters to improve its stability to flow effects are discussed.
