摘要：A stabilising device for a satellite tracking communications aerial comprises a first element which depends from the frame of the aerial and a second element which carries at its lower end one or more rollers arranged to run along the downwardly facing surface of a rail. The first element carries a plate and the second element carries plates. A spring extends between the plates so that the rollers are biased into contact with the surface and any tendency of the aerial to rise is resisted by the action of the spring of the plate.
