Abstract

Abstract An integral antenna for use in receivers and/or transmitters includes a split swivel ball with a through bore for slidably receiving an extendible, telescopic antenna rod held by an internal spring. The antenna rod slides over a removable insert stud having stop pins which engage the swivel ball to normally prevent withdrawal of the rod. To replace the antenna rod without disassembly of or internal access to the swivel ball, the stop pins are manipulated through tortuous bayonet slots contiguous with the through bore to allow the stud and connected rod to be slid through the bore.
