Abstract
A telescoping antenna has a first hollow tubular coiled spring and a second hollow tubular coiled spring with a relatively consistent diameter from a distal end to a proximal end. The second spring is nested inside the first spring when in a stored position. A shim is coupled to a proximal end of the second spring. A diameter of the shim is greater than the diameter of a second spring.
Claims20
An antenna comprising:
- a first flexible tubular coiled spring;
- and
- one or more additional flexible tubular coiled springs, wherein a diameter of the one or more springs is generally less than a diameter of the first spring so the one or more springs can be nested serially within the first spring;
- wherein the first and one or more springs are telescoping elements and radiating elements, and at least a portion of the first and one or more springs is exposed when the antenna is in an extended position.

A telescoping antenna comprising:
- a first hollow tubular coiled spring;
- a second hollow tubular coiled spring having a relatively consistent diameter from a distal end to a proximal end, wherein the second spring is nested within the first spring when in a stored position;
