1 Claim. (Cl. 343-835) This invention relates to television antennas or the like and particularly pertains to a tubular pole having a radially spaced co-axial feeler rod axially adjustable relative thereto and means for adjusting the plane thereof.

Antennas have been employed heretofore to facilitate the receiving of various electrical signals. However, the several devices ofthe prior art have not proven entirely satisfactory inasmuch as they are complicated in design and construction, expensive to manufacture, difficult to use and sometimes are not suitable tothe particular area in which they are used.

With the foregoing in view, the primary object of the invention is to provide a television antenna or the like which is simple in design and construction, inexpensive to manufacture, easy to use, and easy to mount and adjust so as to be rendered suitable for any locality.

An object of the invention is to provide a tubular pole which is endwise or axially adjustable relative to its terminal take o point for adjusting the amount of signal transmitted to the terminal, or, conversely, for adjusting the amount of pole used to sense or receive the signals.

An object of the invention is to provide a feeler rod coaxially disposed and radially spaced from the tubular pole which is axially adjustable for varying the intensity and for balancing the reception of the pole.

An object of the invention is to provide a semi-universally mounted head for supporting a pole or group of poles thereon so as to be capable of placing the poles in the desired plane.

An object of the invention is to provide a rotating clamping means on the mast head for Irotating or swinging the poles relative to a particular station from which they are to receive a signal.

An object of the invention is to provide pivotally mounted antenna lead cases leading from the mast head for adjusting the plane or position of the leads contained therein to further clear and tune the signal received by the poles.

An object of the invention is to provide tongue and groove leads particularly suitable for grouping together below the case area of the leads so as to align the leads to prevent the occurring of resistances and fields in the leads themselves.

.These and other objects of the invention will become apparent by reference to the following description of the antenna device embodying the invention taken in connection with the accompanying drawing in which:

Fig. l is a side elevational view of the inventive device.

Fig. 2 is a top plan view of the device seen in Fig. l taken on the line 2 2 thereof.

Fig. 3 is a cross-sectional view of the lead case taken on the line 3-3 of Fig. 1.

Fig. 4 is a cross-sectional view of the tongue and groove lead wires taken on the line 4-4 of Fig. lj and Fig. 5 is a cross-sectional view of one pole taken on the line 5-5 of Fig. 2.

Referring now to the drawing wherein like numerals refer to like and corresponding parts throughout the several views, the antenna device disclosed therein to illustrate the invention comprises a mast 10, a transverse head 11, a ball and socket joint 12 semi-universally securing the head 11 on the mast 10, a foot 13 adjustably disposed on the mast 10 such as by the slot and bolt connections therebetween including the slot 14 in the mast 10 and the slot 15 in the foot 13 and the bolt 16 connecting same together.

The slotted lead cases 17 are pivotally disposed between the head 11 and the foot 13 and are adapted to receive the leads 18 therein. The mast 10, head 11,`

foot 13, and cases 17 are preferably made from insulating material such as wood, but may be made of metal and necessary insulations added to isolate the antenna portions carried on the head 11 and the leads coming therefrom. The ring clamps 19 have a shank portion 20 rotatably disposed in the head 11 and the head has a saucer-like portion 21 adapted to 4receive the base of the ring portion 22 of the clamp 19 and it -is to be noted that the clamp 19 is rotatably disposed on the head 11.

Disposed Within the clamps 19 are the tubular poles 23 which are endwise or axially slidably disposed in the ring clamp terminals 19 and are tixedly mountable therein by tightening the nut 24 on the shaft 20 so that the poles 23 are axially movable relative to the terminal position of the clamp 19 thereon and are swingably mounted with the clamp 19 to vary their position on the head 11. The collar 24 is disposed within the pole 23 and the feeler rod 25 is disposed with the collar 24 with the set screw 26 threaded in the collar 24 and is adapted to abut the rod 25 and hold same in an axially adjusted position relative to the tubular pole 23 in which it is coaxially disposed and radially spaced therefrom.

The tongue and groove leads 27 are equipped with mating tongues 28 and grooves 29 so that they can be intertted in xed relation so that the wires 30 and 31 contained therein can be aligned without 'twisting or turning so as to prevent the formation of interferences and fields occasioned by twisting. Referring to Fig. 2 it will be noted that the poles 23 are disposed in varying angular positions relative to the head 11 and to each other and that the feeler rods 2S are endwise co-aXially adjusted relative to the tubular poles 23 at varying selective distances and degrees.

'Ihe rods 25, collar 24, and tubular poles 23 are electrically conducting material as are the ring clamps 19 so that a signal received by the pole 23 and rod 2S is transmitted :to a selector switch via the ring clamp 19, the lead 18 which is disposed between the terminal portion of the ring clamp 19, and the element 30 of the tongue and groove leads 27 disposed below the foot 13; the lead 18B is disposed like the lead 18A but is connected to an adjacent pole Ias a reflecting medium.

The leads 18A and 18B emanate from the elements 30 and 31 of the lead 18 which, in turn, transfer from the leads 27; the other end of the elements 30 and 31 at the base of the leads 27 are integrated in a selector switch. The lead 18A from each lead 18 is connected to one pole while the lead 18B from each lead 18 is connected to an adjacent pole. The switch connections are such, as is'well understood in the art, that when a station is selected, the leads 18A and B'to an adjacent pole are connected to the signal impact of the set.

After the applicator has assembled the device as seen in Fig. l, he mounts the mast 10 on a building and then tilts and moves the head 11 on the universal joint 12 to the desired plane which particularly suits the locality lead cases 17 therebetween and angularly Vrotates theV poles 23 Ithereon to pickup the desired signals and axially adjusts each pole 23 relative to the terminal clamp 19 and axially adjusts each `feeler rod 25 relative to each pole 23 ,and it A the pole 23 relative to the terminal 19' and the Afeeler rod relative to the pole 23, that signal is received.

After the poles 23 and'rods- 25 are adjusted as to plane, angle, and axial extent,.the lead cases 17 are angularly rotated relative to the poles 23 so as to eliminate interference and gain advantageous reflection.

It is to be noted that the poles 23 are disposed both on top of and below the head 11, Figs. land 2, so that they can be angularly rotated and Vaxially extended with out interfering with one another. Thev lead cases 17 are preferably six feet long so as to space the leads apart for this distance below the head 11 and poles 23- so as to eliminate interference therebetweenr It has been vfound that this spacing is-very advantageous in this area below the head 11 and it has also been found that grouping the leads as seen in Figs. l and 4 below this area does not t interfere With reception.

Each pole 23 is preferably adjusted to receive signals from Aone or possibly more stations and it has been found advantageous to so co-ordinate the poles and stations that one pole acts as a reector for the other.

The leads 27 are integrated in a multiple selector switch, not shown, so thatwhen a certain station is selected on the TV set, or a like device such as FM radio, the poles adjusted for the certain station are connected' to the set land the remaining poles disconnected.

The inventive antenna with these features constitutes'V a compact, durable, and neat appearing mechanism easily adjusted to receive clear strong electrical signals.

has been foundthat lwy'adjus'ting` a strong iinely toned t Although but a single embodiment of the invention Y has been shown and described in detail, it is obvious that many changes may be made in the size, shape, detail, and arrangements of the various elements of the invention'within the scope of the appended claim.
