Abstract
Abstract An elongated, rigid, television frequency antenna of the dipole type, for indoor reception use, including a long, flexible, lead-in or transmission line for connection to a television set, the antenna itself being otherwise physically free, with no supporting structure of its own, so that it may be disposed in innumerable positions, or diverse orientation within a room, for maximum reception. Both of the dipole elements are enclosed within a single plastic, elongated sturdy tube resembling a stick, for facilitating selective and desired orientation of the antenna, and supported in such orientation by the floor, or walls of the room. The transmission line is also so connected to the dipole that it modifies the characteristics of one half of the dipole more than the other, thus providing greater choice of orientation.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
190 words
An indoor television antenna comprising a rigid, elongated antenna body, said body being hollow, tubular, and formed of electrically insulating plastic material, a coiled spiral conductive elongated antenna element device for receiving broadcast directional television frequency waves and disposed within and substantially throughout the length of said body to define a dipole, and an elongated flexible transmission line having at least two conductors, one end of said line with its said conductors entering one end of said body and its said conductors at said one end of said line being connected to said dipole antenna at a central portion, and the conductors at the other end of said line being adapted for connection to the input system of a television receiver, the length of said transmission line between said one end of said body, and said other end of said line being greater than the length of said body, said body being free of supporting structure other than its own rigid tubular form and its said transmission line whereby said body may be freely physically oriented in any position of reception limited only by its end connection to said line.
Claim 2
Dependent Claim
190 words
An indoor television antenna comprising a rigid, elongated antenna body, said body being hollow, tubular, and formed of electrically insulating plastic material, a coiled spiral conductive elongated antenna element device for receiving broadcast directional television frequency waves and disposed within and substantially throughout the length of said body to define a dipole, and an elongated flexible transmission line having at least two conductors, one end of said line with its said conductors entering one end of said body and its said conductors at said one end of said line being connected to said dipole antenna at a central portion, and the conductors at the other end of said line being adapted for connection to the input system of a television receiver, the length of said transmission line between said one end of said body, and said other end of said line being greater than the length of said body, said body being free of supporting structure other than its own rigid tubular form and its said transmission line whereby said body may be freely physically oriented in any position of reception limited only by its end connection to said line.
Claim 3
Dependent Claim
51 words
An indoor television antenna according to claim 1 and including an end cap of insulating material at each end of said body, and a diametrically enlarged outer rim on each cap for jointly elevating said body over a support for said body when said body is horizontally disposed on said support.
