ABSTRACT:
A user replaceable flexible retractable antenna for use with a cordless phone comprises a conductive base pipe assembly having a screw terminal to be threadably received on a bracket assembly of the cordless phone, and a flexible antenna assembly having a conductive contact secured to one end slidably received within the base pipe assembly. The contact is maintained in sliding communication with the inner wall of the base pipe assembly and is connected to a conductive helix extending through the flexible antenna to define a conductive path between the distal end of the flexible antenna and the screw terminal of the base pipe assembly. The antenna can be easily removed from the cordless phone by rotating the base pipe assembly to disengage the screw terminal from the bracket assembly.
