ANTENNA SUPPORT Filed Jan. 22, 1942 45 Ilgw I IN VEN TOR.
fM/Af R raw/170m A TTORNEY Patented Sept. 30, 1947 ANTENNA SUPPORT Emile R. Touraton, Lyon, France, assignor to International Standard Electric Corporation, New York, N. Y., a corporation of Delaware Application January 22, 1942, Serial No. 427,708 In France April 13, 1940 2 Claims. 1
The invention relates to means for providing a continuously tensioned feed line for an antenna and at the same time relates to means to avoid losses in the insulating pieces and tensioning elements and thus eliminate irregularities caused by variations in the spacing of the wires.
The invention will be explained with reference to the enclosed drawings in which Fig. 1 represents an embodiment of the transmission line; and
Fig. 2 represents an embodiment of the insulating and supporting elements.
In Fig. 1, the transmission or feed line conductors are shown at 40. They may be, for example, bronze telephone lines having a diameter of 6 mm. At equal distances of there are provided spacing insulators 4|, at intervals, e. g. every 5 there are provided spacing and guiding insulators 42 which are therefore located in planes where the high frequency potential is zero. These insulators are arranged in such a manner that the tension of the conductors will produce no strain on the insulating element, and the supporting insulators are so arranged that the connecting elements are located in a plane where the field is practically zero and where, on this account, these elements cannot cause losses or heating.
Fig. 2 represents an embodiment of a supporting or guiding insulator.
This insulator comprises a rod 43 of insulating material. At each end. this rod is provided with a. copper cap 44 sealed with brass. The conductors are fastened to the cap 44 by means of a flexible band 45. On account of the relative flexibility of this mounting, no tensioning strain is applied to the insulating material. The presence of the cap 44 makes possible high electric discharge potential, particularly when the insulator is wet. At the middle of the rod 43, I attach a transverse bar having a larger crosssection and terminated by two parallelopipeds 41 which are perforated at 48. The fixation is, e. g. by means of enamel and, in order to insure correct location after baking, grooves are provided in the two pieces wherein an insulating wedge is provided. The supporting cables 49 pass through the holes 48 and are attached to the supports, not shown. As already explained, they are in a plane where the high frequency potential is zero. The insulators 50 as well as the springs 52 are provided with tensioning elements 51 in the mounting system.
The spacing insulators are constituted by rods like the rods 43 shown in Fig. 2, but without the supporting element 46 and they have the same capacity characteristics as the guiding insulators eliminating all line irregularity.
The arrangement thus described makes possible the application to the conductors of the transmission line of tensions of several hundred kgs.
This high tension may be applied without subjecting the spacing elements to high strains and these elements are placed under no mechanical strain whereby I avoid the irregularities caused by variable spacing produced by temperature, wind, and other variable factors.
What is claimed is:
1. In combination with a high frequency feed line for an antenna, said line including a pair of parallel line conductors having transversely aligned points of zero high frequency potential, a support including an insulating spacing rod in a plane normal to said conductors and fastened to said conductors at said points thereon of zero high frequency potential, a bar at right angles to said rod and attached intermediate its ends to the middle of said rod, and means for supporting said bar in a plane normal to said transmission line conductors.
2. The combination according to claim 1 in which each end of said bar terminates in a parallelopiped having a cable perforation therethrough.
