Abstract

The system has several antennae and several directional radiation patterns. At least two patterns have a zero in the direction of the ship's long axis, and extending over the entire vertical plane through this axis. The advantage lies in preventing the mast from affecting navigation. Two frame antennae (I,II) have their planes vertical and parallel to the ship's long axis and each produces a dipole voltage and a frame voltage which are combined with those of the other antenna. Two further antennae (III,IV) may be provided to give a crossed arrangement. The system can be used with a conventional 2-channel display (24).
