Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
117 words
An antenna for receiving signals in the television band, comprising: a conductor wound about a linear axis to form an elongated helix, an elongated hollow cylindrical member of non-magnetic metal located within said helix in non-contacting relation with said conductor and extending substantially the length thereof, said cylindrical member being closed at one end by a plate of non-magnetic metal, one end of said conductor being electrically connected to said cylindrical member adjacent said closed end, a layer of electrical insulating material supported by said helix, a metallic foil sheet wrapped directly about said insulating layer, a first electrical terminal connected to said one end of the conductor, and a second electrical terminal connected to the foil.
Claim 2
Dependent Claim
117 words
An antenna for receiving signals in the television band, comprising: a conductor wound about a linear axis to form an elongated helix, an elongated hollow cylindrical member of non-magnetic metal located within said helix in non-contacting relation with said conductor and extending substantially the length thereof, said cylindrical member being closed at one end by a plate of non-magnetic metal, one end of said conductor being electrically connected to said cylindrical member adjacent said closed end, a layer of electrical insulating material supported by said helix, a metallic foil sheet wrapped directly about said insulating layer, a first electrical terminal connected to said one end of the conductor, and a second electrical terminal connected to the foil.
Claim 3
Dependent Claim
22 words
An antenna according to claim 2 wherein said one end of the conductor is adjacent the closed end of the cylindrical member.
Claim 4
Dependent Claim
19 words
An antenna according to claim 2 wherein said conductor is wound on a rigid form of electrical insulating material.
Claim 5
Dependent Claim
32 words
An antenna according to claim 3 including a container of insulating material housing said antenna, a pair of contacts extending through a wall of said container, and respectively connected to said terminals.
Claim 6
Dependent Claim
11 words

Claim 7
Dependent Claim
29 words
An antenna according to claim 1 wherein said conductor is wound on a rigid form of electrical insulating material, the turns of the helix being closely adjacent each other.
Claim 8
Dependent Claim
18 words
An antenna according to claim 5 wherein said helix comprises 24 to 40 turns of No. 18 wire.
Claim 9
Dependent Claim
27 words
An antenna according to claim 1 wherein said second electrical terminal is connected to the foil at a location adjacent the open end of said cylindrical member.
