Abstract
Abstract There is disclosed a method for manufacturing a television antenna, as well as a television antenna which is manufactured according to the preferred method. The television antenna of the preferred embodiment comprises a layer of flexible non-conductive material, such as mylar, on top of which is affixed a plurality of strips of flexible conductive material. Electrical leads are connected to the flexible strips of conductive material and the entire flexible structure is then placed on a rigid housing. In the preferred embodiment, the rigid housing comprises a circular non-conductive shell. The flexible layer of laminated conductive and non-conductive material is placed circumferentially around the interior of the circular shell, thereby forming an omnidirectional antenna which is completely impervious to corrosive elements.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
131 words
An omni-directional television receiving antenna comprising: a layer of flexible non-conductive material; a plurality of parallel strips of flexible conductive material having a preselected substantially equal length wherein each of said strips of flexible conductive material includes a first end and a second end and wherein each of said strips of flexible conductive material are affixed to said layer of flexible non-conductive material; first means for electrically connecting said strips of flexible conductive material to a utilization device; and a rigid non-conductive circular housing wherein said layer of flexible non-conductive material is affixed to the interior of said housing whereby said first end of each of said conductive strips is placed adjacent to its respective second end of said conductive strips thereby forming a plurality of substantially circularly shaped conductive elements.
Claim 2
Dependent Claim
131 words
An omni-directional television receiving antenna comprising: a layer of flexible non-conductive material; a plurality of parallel strips of flexible conductive material having a preselected substantially equal length wherein each of said strips of flexible conductive material includes a first end and a second end and wherein each of said strips of flexible conductive material are affixed to said layer of flexible non-conductive material; first means for electrically connecting said strips of flexible conductive material to a utilization device; and a rigid non-conductive circular housing wherein said layer of flexible non-conductive material is affixed to the interior of said housing whereby said first end of each of said conductive strips is placed adjacent to its respective second end of said conductive strips thereby forming a plurality of substantially circularly shaped conductive elements.
Claim 3
Dependent Claim
24 words
The omni-directional antenna of claim 1 further comprising: second means for electrically connecting a preselected number of said parallel conductive strips to each other.
Claim 4
Dependent Claim
29 words
The omni-directional antenna of claim 2 wherein said second means comprises a strip of conductive material affixed to said first ends of each of said preselected parallel conductive strips.
Claim 5
Dependent Claim
22 words
The omni-directional antenna of claim 1 wherein said antenna comprises 11 parallel strips of flexible conductive material affixed to said non-conductive material.
Claim 6
Dependent Claim
57 words
The omni-directional antenna of claim 4 further comprising: second means for electrically connecting together the first ends of four of said conducting strips thereby forming a first group of conductive elements; and third means for electrically connecting together the first ends of the remaining seven of said conducting strips thereby forming a second group of conductive elements.
Claim 7
Dependent Claim
67 words
The omni-directional antenna of claim 5 further comprising: a means for electrically bisecting one of said strips of conductive material of said second group of conductive elements whereby one of said bisected segments remains electrically connected to said third means; and fourth means for electrically connecting the other of said bisected segments to another of said strips of conductive material in said second group of conductive elements.
Claim 8
Dependent Claim
25 words
The omni-directional antenna of claim 6 wherein said flexible non-conductive material comprises mylar and wherein said flexible strips of conductive material each comprise copper foil.
Claim 9
Dependent Claim
26 words
