Abstract

PURPOSE:To make the test and maintenance for a communication circuit and its relating components easy, by constituting in such a way that the titled antenna is used as a normal antenna at antenna extension, and antenna transmission and receiving terminals are connected to a dummy load at contraction. CONSTITUTION:A free end of a sleeve at the innermost side of a rod antenna main body 10 consisting of a plurality of conductive sleeves combined extendably and contractably is provided with a top metallic screw member 12. A lower end of the outermost sleeve of the main body 10 is provided with a terminal 14 to be connected to an antenna lead and the outer circumference is covered with an outer conductor tube 18. A lower end of the tube 18 is provided with a terminal 20 and an upper end is fitted with a dummy load member 22. A screw member 26 of the member 12 is conducted and latched to a screw 24 of the member 22 at antenna contraction. This member 12 acts like a cap inserted to the member 22 and connects the base 10 electrically to the member 22.

ナを提供することである。The present invention organically combines this rod antenna and a member that functions as a dummy load, and forms a circuit in which the antenna is connected as a normal antenna when it is extended, and is connected to the dummy load at the power transmitting and receiving end of the antenna when it is contracted. By constructing the eutectoid board member with an elastic material, it is possible to easily test and maintain the communication circuit and its related parts. To provide a rod antenna with a dummy load.
