<p>PURPOSE:To fold the titled system into a small size at storage and to eliminate the need for a gas injecting device required for a buoy by forming the antenna with a spring conductor and giving a floating force by a floating boat made of a foamed plastic. CONSTITUTION:The antenna system 10 consists of the floating boat made of a foamed plastic, an antenna 12 formed by a spring conductor formed in a circle in the floating boat 11, a connecting part 13 connecting the floating boat 11 and the antenna 12 and a radio equipment 14 connected electrically to the antenna 12 by a cable 15. The antenna 12 is fixed to a fixed part 19 via a fixed rod. Through the constitution above, the radio equipment 14 acts like a weight and the stability against waves is improved. Further, the antenna 12 is, for example, folded by a folding part 21 and stored in a storage case 22. The case 22 is of double-cut structure. Thus, miniaturization and simplicity are attained.</p> |
