Definitions

• Another object is to provide a new and improved indoor antenna of the character indicated which can be secured to the back of a picture which can be mounted on a wall adjacent a television receiver.
• a further object of this invention is to provide an improved selectively variable antenna which has one oval and two rectangular loops for three separate ranges of reception and which are coplanar so as to be adapted to be attached to the back of a picture or the like.
• Another object of this invention is to provide an improved selectively variable antenna wherein two loops thereof have perpendicular grid members to effectively provide a composite grid work when the two loops are electrically interconnected.
• FIGURE 1 is a perspective view of the invention as connected to a television receiver.
• FIGURE 2 is an exploded view of the parts of the invention as incorporated in a picture and frame.
• FIGURE 3 is a modified form of the invention wherein the frame is omitted.
• FIGURE 4 is a fragmentary circuit diagram of the invention.
• FIGURE 5 is a further fragmentary circuit diagram of the invention.
• the antenna input terminals of a television receiver are connected to an antenna which comprises a picture 11 mounted on a sheet 12 of Masonite mounted within a frame 14. Secured to the back of the sheet 12 is a length of hollow copper tubing 0/4" in diameter) formed into a first loop 16 defining the periphery of an almost complete rectangle having free ends 18 and 20.
• a second length of hollow copper tubing in diameter is also secured to the back of sheet 12 and disposed within the periphery of the first loop to form a second loop 22 also defining the periphery of an almost complete rectangle having free ends 24 and 26.
• Four short lengths of tubing 28 are secured to loop 22 at spaced apart positions at an angle of 45 thereto.
• a third length of hollow copper tubing in diameter is also secured to the back of sheet 12 and disposed within the periphery of the second loop 22 to form a third loop 30 and defining the periphery of an almost complete kidney having free ends 32 and 34.
• Eight separate brass rods 36 are secured to loop 30 and extend in a direction perpendicular to lengths 28. Seven of these rods 36 are inch in diameter. The eighth rod 38 is /8 inch thick.
• I further provide a two pole, three position manual switch 40 as shown in FIGURES 4 and 5.
• the arms 42 and 44 of switch 40 are connected to the antenna input of the receiver.
• Arms 42 and 44 are gauged and can be 3,261,019 Patented July 12, 1966 ice respectively connected to either of terminals 1, 2 or 3 to permit different portions of the antenna to be connected to the receiver.
• the antenna loops can thereby be separately connected to the television antenna input or connected thereto in pairs depending on which terminals are interconnected.
• Ends 32 and 34 are connected to opposite terminals 1. Ends 24 and 26 are connected to opposite terminals 2 and end 26 is connected to loop 30. End 34 is also connected to one terminal 3. End 26 is connected to this one terminal 3. Ends 18 and 20 are connected to opposite terminals 3.
• An antenna to be connected with two television receiver antenna input wires comprising a first oval-shaped loop of electrically conductive tubular material mounted on the surface of a non-conductive sheet and having two end terminals extending from one side of said first loop substantially perpendicular to the larger axis of said oval and coplanar with the loop, spaced-apart pieces of conductive tubing electrically secured to said first loop thereacross at a 45 angle to said longer axis of said loop, a second loop of rectangularly-shaped electrically conductive tubular material mounted on said surface of said sheet and having two end terminals extending perpendicularly to one side of said second loop in coplanar manner with said first loop and outwardly from said end terminals of said first loop, spaced-short pieces of conductive tubing secured to said second loop in conductive manner therewith across sides thereof and perpendicular to said spacedapart pieces on said first loop, a third loop of rectangularly-shaped electrically conductive tubular material mounted on said surfaces of said sheet having two end terminals extending perpen
