Abstract

PURPOSE:To maintain the antenna characteristic by forming an antenna tip through the integral forming of a metal extruded member and a loading coil at the tip of the antenna with a rubber group elastomer. CONSTITUTION:The antenna tip 5 is formed by integrally forming a metal extruded member 2 and a loading coil 4 provided at the tip of the antenna main body 1 made of a resin-made pipe with a rubber elastomer. Thus, an elasticity is provided to the antenna tip 5 to improve the strength of the tip 5 and it is prevented that the coil 4 is permanently deformed by the elasticity of the tip 5 thereby maintaining the antenna characteristic.
