WHIP-TYPE ANTENNAE Filed Sept. 7, 1951 INVENTOR. J/ic/r M 5/71/15.
United States Patent WHIP-TYPE ANTENNAE Jack M. Davis, Lake Placid, N. Y.
Application September 7, 1951, Serial N 245,445?
3 Claims. (Cl. 25tl--33) This invention relates to whip-type antennae and particularly to an antenna for television reception.
It is an object of this invention to provide a low cost, lightweight and easily installed whip-type antenna which may be used for both high and low frequency reception, and which is designed for any two separate and different frequencies, not necessarily harmonically related, for simultaneous or separate operation thus saving space, material and construction cost and providing greater flexibility of operation.
A further object of the invention is to provide such an antenna having combined high and low frequency loops which are connected together in a compact and space saving manner.
A still further object of this invention is the provision of a whip-type antenna having novel means for quickly and securely mounting it on a window of a building or on a similar supporting structure.
Further objects and advantages of this invention will be more clearly understood from the following description and the accompanying drawings in which:
Fig. 1 is a side view of a whip-type antenna embodying my invention, the same being shown as attached to a window of a building.
Fig. 2 is a diagrammatic view showing the electrical elements for said antenna.
Fig. 3 is a plan view illustrating the adjustable mounting means whereby said antenna is secured to a window.
Fig. 4 is a side view of a modified form of said mounting means.
As shown in the drawings, my improved antenna is preferably constructed in the form of a whip that comprises a rod of a suitable insulating material, such as polystyrene, Lucite or fiberglass, which forms a lightweight and weatherproof covering for the antenna elements; said elements being preferably constructed of wire loops that are suitably placed and imbedded within the said rod and electrically insulated from each other, by the material forming the rod, to insure the eflicient reception of television signals. The mechanical and electrical properties of the conductors and insulating material are so engineered that they provide a proper impedance match and frequency resonant condition for both present and future TV channels.
The said antenna includes lead wires 66 which enter the rod through bosses 7-7, that are formed integrally therewith, and said lead wires are attached at the proper feed points as shown in Fig. 2.
The antenna elements, illustrated in Fig. 2, include a low frequency band dipole in the form of a loop 8 having legs 9-9 which extend inwardly from the ends of said loop and have their inner ends connected to the lead wires 6-6.
The said antenna also includes a high frequency band dipole loop 10 which is connected at the ends thereof to intermediate points of the legs 9-9 so that the said high frequency band loop includes inwardly extending legs 9a9a each of which comprises a portion of the legs 9--9 of the low frequency band loop 8.
By means of the above described construction, wherein a portion of the low frequency loop is also used as a portion of the high frequency loop, the said antenna is so materially reduced in size that it can be contained within a rod 5 of a substantially small diameter thereby providing a whip-like antenna which is inexpensive to produce, efficient in its operation and adapted to be securely mounted on a window sill or other supporting structure.
As shown in Fig. 3, my improved antenna is provided with adjustable mounting means which include a base 11 that is secured to the inner end of the rod 5 and is connected to a tubular supporting bar 12 having a foot 13 that is adapted to engage one of the sides of a window opening, indicated at l414. A threaded adjusting bar 15 extends into the tubular bar 12 and has a nut 16 threaded thereto which abuts the end of the bar 12 so that the said bar 15 may be adjusted, by the rotation of said nut, to press the foot 13-a thereof against the opposite side of the window and thereby securely mount the antenna thereon.
A supporting extension 17 is preferably provided on the base 11 and extends therefrom to engage the top of the window sill, which is indicated at 18, to support the antenna in an outwardly extending position. The angle of the antenna to the vertical plane may be adjusted as desired by simply raising or lowering the position of the base it relatively to the top of the window sill.
If desired, the mounting means may be constructed as shown in Fig. 4 wherein the base member 19 has a foot 20 which is swivelly secured to a supporting clamp memher by means of a clamping screw 22. With this modified form of clamping means, the antenna may be adjusted at any desired angle on a horizontal as well as on a vertical plane to permit reception of either horizontally or verticaily polarized Wave propagation.
I claim:
1. An antenna comprising an elongated rod of insulating material having imbedded therein a low frequency band loop having opposed inwardly extending leg portions, a high frequency band loop adjacent said first loop and having its legs formed by portions of the legs of said first loop, and a pair of lead conductors for said low and high frequency loops connected to the inner ends of said common leg portions and extending outwardly therefrom to the exterior of said rod.
2. An antenna comprising an elongated rod of insulating material having mounted therein a low frequency band loop with end portions thereof bent inwardly and forming opposed leg portions, a high frequency band loop having its ends connected to intermediate points of said leg portions, the inner parts of said leg portions providing leg portions for the high frequency loop, and a pair of lead conductors for said low and high frequency loops connected to the inner ends of said common leg portions and extending to the exterior of the said rod.
3. An antenna comprising a low frequency band folded dipole loop having inwardly directed, opposed leg portions, an adjacent, coexisting high frequency band folded dipole loop, portions of the inwardly directed legs of said low frequency loop forming the legs of said high frequency loop, and lead conductors for said low and high frequency loops connected to the inner ends of said common leg portions.
