IRON POLE FOR ANTENNA FORMED TO SIMULATE NATURAL TREE

摘要

PROBLEM TO BE SOLVED: To eliminate a sense of incongruity generated through construction of an iron pole for an antenna by placing branch members around a support pole made of a hollow steel pipe and coating the surface of the support pole and the branch members with a coating material so as to form an artificial tree like a natural tree and placing an antenna on top of the simulated tree thereby allowing the simulated tree to be well in matching with a natural scenery in a mountain range. ;SOLUTION: Hollow steel pipes 2 connected forms the support pole 1. The diameter of the steel pipes 2 is selected to become smaller toward the top of the pole 1 so as to allow the pole 1 to be well in matching with an outward appearance of a natural tree. The branch members 3 being metal-made pipes are welded to required parts of the steel pipes 2. A horizontal plate 6 is welded to a tip of an antenna mount branch 5 placed to an upper part of the support pole 1 and an antenna mount bracket 7 whose cross-section is L-shaped is provided onto the horizontal plate 6. Furthermore, cable insertion rings 9 are fitted to an outer circumference of the support pole 1 at a proper interval at their bases of the rings 9 by welding or other method. Then a reception antenna is fitted to the top of the support pole 1 and the antenna mount bracket 7.;COPYRIGHT: (C)2000,JPO
