An extendable antenna assembly allows for snap-in assembly and quick disconnection thereby saving both time and money in antenna assembly and replacement. The extendable antenna assembly includes an extendable radiating half-wavelength antenna (108) and a helical quarter wavelength antenna (300). The helical antenna (300) includes an antenna section (112) and a support section which includes a number of resilient leg members (116). Some of the leg members (116) include snaps (118) which engage with retention areas (122) which are found in the radio housing (120). A guide tube (102) having a flared top section (124) is found inside the radio (100) and provides for a way of compressing the individual leg members (116) thereby, releasing the extendable antenna assembly from the radio housing (120) when the antenna assembly requires removal.
