Abstract

Abstract An antenna which is constructed exclusively of fiberglass, with the sole exception of the electrical conductors, couplings, and upper and lower ends, which may incorporate fiberglass or some other material, which antenna is constructed in a series of lengths, or in a single length in the case of a very short antenna, each of the lengths being essentially of hollow tubular construction, with the walls of the tube made up of alternate layers of glass fiber filaments, one such layer being made up of filaments extending longitudinally along the axis of the antenna, and the next such layer being made up of filaments which are wound spirally around the antenna, anywhere from four to twelve or more such layers being employed one upon the other, and in which the antenna base is constructed with at least the longitudinal glass fibers being formed into a generally bellshaped base member, and incorporating a reinforcing core of which may be fiberglass or some other material with such longitudinal fibers extending through a central opening in the core, and then being folded backwardly around the exterior of the core, and led alongside the exterior of the antenna itself for a predetermined distance, the exterior of the core and fiberglass filaments extending therearound, being formed into a suitable base shape, by means of an exterior mould which is clamped therearound under pressure during curing of the resin.

Claims Analysis

Total Claims: 8

Claim 1

Independent Claim 86 words

A free standing antenna device as claimed in claim 1 including endwise extensions of some of said longitudinally extending strands of said glass fiber filaments extending through said cylindrical opening of said core member, said endwise filament extensions being folded around the exterior of said support surface and said core member and back up alongside a portion of said main body portion and bonded thereto and to said core member whereby to secure said core member integrally with said base end of said main body portion.

Claim 2

Dependent Claim 38 words

A free standing antenna device as claimed in claim 1 wherein said main body portion comprises upper and lower body sections separable from one another for shipping and storage, and when assembled together, forming said main body portion.

Claim 3

Dependent Claim 95 words

A free standing antenna device as claimed in claim 3 wherein said lower body section has lower and upper ends, said lower end comprising said base end of said main Body portion, and including coupling means on said upper end of said lower body section, and wherein said upper body section defines lower and upper ends, said upper section upper end defining said upper closed end of said main body portion, and coupling means on said upper section lower end for interengagement with said coupling means on said upper end of said lower body sections.

Claim 4

Dependent Claim 37 words

A free standing antenna device as claimed in claim 4 wherein said coupling means comprise a male exterior threaded coupling member on one said end, and a female interior threaded coupling member on the other said end.

Claim 5

Dependent Claim 75 words

A free standing antenna device as claimed in claim 4 including electrically conductive means extending along the length of each of said upper and lower body sections, said conductive means terminating at said coupling means, and including contact ring means incorporated in said coupling means, electrically connected with said electrically conductive means, and adapted to interengage with one another and make electrical connection through said coupling when said coupling means are interengaged with one another.

Claim 6

Dependent Claim 49 words

A free standing antenna device as claimed in claim 4 including at least one intermediate body section between said upper and lower body section, and coupling means at each end of said intermediate body section for interengagement with adjacent coupling means on adjacent said upper and lower body sections.

Claim 7

Dependent Claim 73 words

A free standing antenna device as claimed in claim 1 wherein said electrically conductive means comprise a plurality of separate electrical electrically conductive strips, said strips being embedded within said integrally bonded filament of said main body portion, along the major portion of their length, said electrically conductive strips being arranged in an extended spiral manner whereby to define at least a partial rotation relative to the axis of said main body portion.

Claim 8

Dependent Claim 102 words

A free standing antenna device as claimed in claim 1, wherein said longitudinally extending filament at least comprise a continuous strand of said filament, said strand being arranged to run from one end to the other of said main body portion along the length thereof and being formed into a loop at each end thereof, at least some of said strands of longitudinal filaments, at said base end of said main body being cut so as to permit incorporation thereof into an integral part of said base end portion, and extension thereof around the exterior of said base end portion as aforesaid.
