Stabilizing jacket for a towed cable or antenna structure

摘要

A stabilizing jacket for a towed cable or antenna structure is operative for preventing rotation of the antenna/cable structure as it is towed through the water. The stabilizing jacket consists of an elongated body having a longitudinal bore extending therethrough for receiving the antenna/cable structure therein. The body may extend along the entire length of the antenna/cable structure and is symmetrical about a vertical median. The body further includes first and second symmetrical deflection vanes which extend outwardly from opposite sides of the body, and first and second symmetrical keel fins which diverge outwardly and downwardly from the body immediately adjacent the median. The deflection vanes and keel fins may extend along an entire length of the body. The symmetrical keel fins effectively increase the metacentric height of the antenna/cable structure and thereby tend to prevent rotation of the antenna/cable structure due to hydrodynamic forces as the antenna/cable is towed through the water.
