Combined television stand and antenna system

Claim 2

A combination table and antenna system for television receivers, said combination comprising a table with a plurality of leg members made of conductive material and forming antenna segments, an upper support surface for supporting a television receiver above said leg members, and means for coupling the input terminals of a television receiver to selected ones of said leg members, said coupling means comprising a plurality of coils connected to said leg members, each of said coils having at least one loop and being arranged with its plane at an angle to the plane of at least one other of said coils, and a pickup coil movable relative to said first-named coils to vary the relative inductive coupling between the pickup coil and the first-named coils and thereby change the direction of maximum sensitivity of said antenna system.

Claim 3

Apparatus as in claim 1 in which each of said leg members has a horizontal conductive member coupled to it by means of an inductor whose impedance is high at UHF frequencies and relatively much lower at VHF frequencies.

Claim 4

Apparatus as in claim 1 in which said leg members are arranged symmetrically in opposed pairs, and in which said coupling means is operable to couple said receiver input terminals to a selected one of said pairs.

Claim 5

Apparatus as in claim 3 in which said coupling means is adjustable to deliver signals from a plurality of said pairs of elements simultaneously, in amounts variable in indefinite increments.

Claim 6

Apparatus as in claim 4 in which said coupling means includes a rotatable knob with an index mark on it, and a dial with corresponding index marks on it positioned adjacent said knob.

Claim 7

A television receiver stand, said stand comprising, in combination, a nonconductive support member, four vertical, symmetrically located legs fastened to said support member, each of said legs being made of conductive material, four horizontal elongated conductive stubs, each being connected at one end to one of said legs, said stubs being arranged in two pairs of opposed stubs, the stubs in each pair being aligned with one another and being perpendicular to the alignment of the other stubs, four inductors, each being connected between one of said stubs and one of said legs, a potentiometer with two opposed wipers and a complete annulus of resistive material making contact with said wipers, each of said stubs being connected to said resistive material at one of four symmetrically located points, and means for connecting said wipers to the input terminals of a television receiver, each of said inductors having an impedance which is high at UHF frequencies and relatively much lower at VHF frequencies.

Claim 8

A television receiver stand, said stand comprising, in combination, a nonconductive support member, four vertical, symmetrically located legs fastened to said support member, each of said legs being made of conductive material, four horizontal elongated conductive stubs, each being connected at one end to one of said legs, said stubs being arranged in two pairs of opposed stubs, the stubs in each pair being aligned with one another and being perpendicular to the alignment of the other stubs, four inductors, each being connected between one of said stubs and one of said legs, a potentiometer with two opposed wipers and a complete annulus of resistive material making contact with said wipers, each of said stubs being connected to said resistive material at one of four symmetrically located points, and means for connecting said wipers to the input terminals of a television receiver, each of said inductors having an impedance which is high at UHF frequencies and relatively much lower at VHF frequencies.

Claim 9

A combination table and antenna system for television receivers, said combination comprising a table with a plurality of leg members made of conductive material and forming antenna segments, said leg memBers being arranged symmetrically in opposed pairs, and means for coupling the input terminals of a television receiver to a selected one of said pairs of leg members, said coupling means including a plurality of fixed coils, each connected to one of said leg members, each having at least one loop of wire, the planes of said loops which are connected to opposed leg members being parallel to one another, the planes of the loops of one pair of elements being perpendicular to the planes of loops of the other pair of elements, and a pickup coil rotatably mounted between said loops, and means for connecting said pickup coil to a television receiver.

Claim 10

A combination table and antenna system for television receivers, said combination comprising a table with a plurality of leg members made of conductive material and forming antenna segments, said leg memBers being arranged symmetrically in opposed pairs, and means for coupling the input terminals of a television receiver to a selected one of said pairs of leg members, said coupling means including a plurality of fixed coils, each connected to one of said leg members, each having at least one loop of wire, the planes of said loops which are connected to opposed leg members being parallel to one another, the planes of the loops of one pair of elements being perpendicular to the planes of loops of the other pair of elements, and a pickup coil rotatably mounted between said loops, and means for connecting said pickup coil to a television receiver.
