Abstract

PURPOSE:To make small the size of the antenna system and to make low the cost, by providing the weight so that the antenna can always be kept vertical at the lower side of the antenna. CONSTITUTION:The wide beam antenna 1 receives the direct wave 2 and the reflection wave 3, and the direct wave only is fed to the receiver from the beam pattern. The antenna 1 has the weight 4 at the lower side and the supports 6, 7 on the way are fixed so that they can freely be turned front and back and left and right. The weight 4 can be in common use with the box allocating the members. The operation of the weight 4 can always keep the antenna 1 vertical and the fading due to the pitching and rolling and to the reflection can be eliminated even with the antenna system loaded on a ship.
