YAGI ANTENNA CAPABLE OF TILTING AND AIMING

摘要

PURPOSE: A YaGi antenna capable of tiling and aiming is provided to be easily installed and controlled in case that the orientation of the antenna is changed due to wind or external impulse or is to be changed at need, thereby reducing the risk to an installer. CONSTITUTION: A radiator for radiating electric waves, a plurality of wave guides axially arranged with predetermined gaps on one side of the radiator, and a reflector formed on the other side of the radiator are integrally manufactured into an antenna device. A connector supplies signals to the antenna device. A bracket(211) is bended into U-shape and a first rotation shaft(214) and a groove(216) on its both sides. A first clamp(212) is inserted into the bracket(211) and has a vertical rotation shaft(215). A second clamp(213) is assembled to the first clamp(212) and has engaging steps(217) on its bottom/top surfaces and fixing holes(218) on its both sides.
