Retractable flexible transmit/receive antenna which operates in a collapsed and extended position

An antenna device comprising:

• an antenna case composed of an inner case and an outer case telescopically assembled together and slidably movable relative to one another so as to extend and contract the length of said antenna case, each of said inner and outer cases being made of an electrically insulating material;
• a metallic terminal attached to an end of said outer case;
• and
• an antenna conductor received in said antenna case and having a coiled resilient portion, said antenna conductor having one end connected to said inner case, and an opposite end electrically connected to said metallic terminal, said resilient coiled portion of said antenna conductor being extendable and contractible in response to the movement of said inner case relative to said outer case.

An antenna device comprising:

• a longitudinal electrically insulated inner case containing therein a coiled conductor which extends over a major portion of said inner case having one end connected to a closed end of said inner case, and an opposite free end extending through a second end of said inner case;
• a slide member closing said second end of said inner case having a through hole which carries said free end;
• an electrically insulated outer case through which said inner case slides, including a means for engaging said slide member retaining said inner case and outer case in one of a plurality of respective telescopic positions;
• and,
• a tension spring connected to apply a retracting force between said inner case and outer case when said inner case and outer case are disengaged, permitting said inner case to be retracted into said outer case.
