United States Patent 3,193,227 ANTENNA MOUNT Watson P. Czerwinski, Shrewsbury, N..l'., assignor to the United States of America as represented by the Secretary of the Army Filed Aug. 30, 1962, Ser. No. 220564 2 Claims. ({Il. 24840) (Granted under Title 35, US. Code (1952), see. 266) The invention described herein may be manufactured and used by or for the Government for governmental purposes, without the payment of any royalty thereon.

The present invention relates to an aerial mounting arrangement and has for its primary object to provide an improved aerial mount suitable for use upon tanks or faster moving vehicles such as jeeps, trucks etc.

It is common practice in radio equipped vehicles to mount a mast or whip antenna that extends several feet above the top of the vehicle, necessitating some form of mounting that will permit the antenna to be deflected when it strikes an obstruction such as an overhanging limb, viaduct, or the like.

The mounts most commonly used that can perform said function usually include a conventional coil or spiral spring which is secured to an appropriate base, wherein the spring is utilized as the deflecting means within the antenna mount. It has been found that antennas so mounted may have undue and undesirable sway in all directions. Such sway or deflection can upset the electrical parameters of the antenna and cause fading. It has further been found that centrifugal forces, particularly when a vehicle having a conventional spring mount makes a sharp turn at fairly high speeds, can whip or lash such antenna considerably outwardly. Such action can constitute a safety hazard to nearby personnel or property.

A feature of the present invention is the arrangement of a novel shape of spring mount so afiixed to a vehicle so as to reduce and substantially eliminate any undue side and lateral motions of the antenna as the vehicle is moving regardless of its speed.

The invention can best be understood from a reading of the following description to be considered in connection with the accompanying drawing in which:

FIGURE 1 is an elevation of the antenna mount of this invention.

FIGURE 2 is a top plan view of the mount shown in FIGURE 1, and,

FIGURE 3 shows the manner in which the mount of this invention is aflixed to a vehicle.

In the drawing, reference is made to FIGURE 3 wherein there is shown a vehicle 11, such as a jeep, which includes a triangular bracket 13 affixed to the rear platform of the jeep. The bracket 13 serves as a support for an 3,i93,22.7, Fatented July 6, I965 "ice antenna and its mount as shown. The mount is shown in detail in FIGURES 1 and 2 and comprises a spring 15 which differs radically from the conventional springs used in antenna mounts of the heretofore available type. As can be seen from an inspection of FIGURE 2, the spring 15 is elliptical in configuration, that is characterized in having a major axis indicated by the dimension B and a minor axis indicated by the dimension A. For securing the antenna 17 within the spring 15, there are provided upper and lower bolts 19 and upper and lower plates 21 provided with openings through which the antenna 17 is engaged. In the specific embodiment herein, the plates 21 are confined within the spring 15 by a force fit. However it is to be understood that the manner in which any plate is confined is no part of the invention herein, and can be held by any suitable means. In the same vein, the manner in which the antenna 17 is held is of no import. In one specific instance, the antenna can be provided with an external threaded base portion adapted to be screwed into internal threads of the bolts 19.

In its utilization the manner in which the spring mount is atlixed to the vehicle is of prime importance. As can be seen in FIGURE 3, the spring mount is so arranged that its long axis is transverse to the direction of travel of the vehicle at all times. A spring mount such as herein described and so arranged will resist side motions of the antenna thus insuring more reliable reception, and substantially eliminate any undue side and lateral whip motions as the moving vehicle makes any sharp swcrving or turning movements.

What is claimed is:

1. An antenna mount for a vehicular body or the like, comprising a base, a spring having a generally elliptical configuration on said base and means associated with said spring for supporting and confining an antenna within said spring.

2. An antenna mount for a vehicular body or the like, comprising a base, a spring, on said base, having an elliptical configuration which includes a major axis and a minor axis and so mounted on said vehicular body that the major axis of the spring is transverse to the direction of movement of said body and means associated with said spring for supporting and confining an antenna therein.
