Abstract
Abstract Two single turn horizontally oriented loops are located in a common plane inside a television receiver cabinet. A multiposition switch is used to connect the loops in various combinations to the receiver antenna terminals. In a typical receiver, employing separate VHF and UHF tuner inputs a fourposition switch is employed. In one position one loop is connected to the VHF input and the other is connected to the UHF input. In the second position the loops are exchanged. In the third position both loops are connected to the VHF input and in the fourth position both loops are connected to the UHF input. Thus for either VHF or UHF reception the user has a selection of three switch positions for optimum signal pickup.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
92 words
A built-in antenna for receiving signals in a television receiver having separate VHF and UHF tuners, said antenna comprising: A pair of single turn loops adapted for mounting horizontally in spaced apart side by side relationship and in a common plane inside the cabinet of said receiver, and means including a switch for connecting said loops to said receiver in combinations including either of said loops singly to either of said tuners and both of said loops connected together to either of said tuners, said switch being positionable for best signal reception.
Claim 2
Dependent Claim
92 words
A built-in antenna for receiving signals in a television receiver having separate VHF and UHF tuners, said antenna comprising: A pair of single turn loops adapted for mounting horizontally in spaced apart side by side relationship and in a common plane inside the cabinet of said receiver, and means including a switch for connecting said loops to said receiver in combinations including either of said loops singly to either of said tuners and both of said loops connected together to either of said tuners, said switch being positionable for best signal reception.
Claim 3
Dependent Claim
94 words
The antenna of claim 1 wherein said switch has four positions, the first position arranged to connect the first loop of said pair to said VHF tuner and the second loop of said pair to said UHF tuner, the second position arranged to connect the first loop of said pair to said UHF tuner and the second loop of said pair to said VHF tuner, the third position arranged to connect said pair of loops to said VHF tuner, and the fourth position arranged to connect said pair of loops to said UHF tuner.
Claim 4
Dependent Claim
23 words
The antenna of claim 2 wherein said loops have a fundamental resonance at a frequency slightly higher than the highest VHF television channel.
Claim 5
Dependent Claim
127 words
An antenna built into a television receiver having separate VHF and UHF input terminals, said antenna comprising: first and second loops disposed horizontally and in a common plane inside said receiver, said loops being oriented in azimuth at approximately right angles with respect to each other, and means, including a multiposition switch, for connecting said loops to said input terminals, said switch having positions which provide for connections including, said first loop connected to said VHF input and said second loop to said UHF input, said second loop connected to said VHF input and said first loop connected to said UHF input, said first and second loops connected in parallel to said VHF input, and said first and second loops connected in parallel to said UHF input.
Claim 6
Dependent Claim
127 words
An antenna built into a television receiver having separate VHF and UHF input terminals, said antenna comprising: first and second loops disposed horizontally and in a common plane inside said receiver, said loops being oriented in azimuth at approximately right angles with respect to each other, and means, including a multiposition switch, for connecting said loops to said input terminals, said switch having positions which provide for connections including, said first loop connected to said VHF input and said second loop to said UHF input, said second loop connected to said VHF input and said first loop connected to said UHF input, said first and second loops connected in parallel to said VHF input, and said first and second loops connected in parallel to said UHF input.
Claim 7
Dependent Claim
22 words
The antenna of claim 4 wherein said loops are constructed of strips of sheet metal having substantial width to provide broadband performance.
Claim 8
Dependent Claim
