Abstract
Abstract A waveguide transmission line comprising a series of sections, each section comprising a section of waveguide disposed within a section of a larger diameter rigid jacket and bound, under tension, at both ends of the jacket. This structure is used to substantially eliminate deflections in short sections of the waveguide. Advantageously, the space between the waveguide and the jacket is filled with a flexible material such as rubber or plastic foam to prevent sag due to gravitational force.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
67 words
A waveguide transmission line comprising a plurality of coupled sections of waveguide structure, each section comprising: a section of waveguide in a state of tension; a section of a rigid outer jacket spaced away from said waveguide; and means at each of the ends of the rigid outer jacket for mechanically coupling said waveguide to said jacket while simultaneously maintaining said waveguide in said state of tension.
Claim 2
Dependent Claim
67 words
A waveguide transmission line comprising a plurality of coupled sections of waveguide structure, each section comprising: a section of waveguide in a state of tension; a section of a rigid outer jacket spaced away from said waveguide; and means at each of the ends of the rigid outer jacket for mechanically coupling said waveguide to said jacket while simultaneously maintaining said waveguide in said state of tension.
Claim 3
Dependent Claim
52 words
A structure according to claim 1 wherein the space between said waveguide and said rigid jacket is filled with a material to reduce sag in the waveguide from gravity, said material being sufficiently flexible that the tension on the waveguide will keep it substantially straight despite small deflections on the rigid jacket.
Claim 4
Dependent Claim
55 words
A waveguide structure comprising: a section of waveguide in a state of tension; a section of a rigid outer jacket spaced away from said waveguide; and means at each of the ends of the rigid outer jacket for mechanically coupling said waveguide to said jacket while simultaneously maintaining said waveguide in said state of tension.
Claim 5
Dependent Claim
55 words
A waveguide structure comprising: a section of waveguide in a state of tension; a section of a rigid outer jacket spaced away from said waveguide; and means at each of the ends of the rigid outer jacket for mechanically coupling said waveguide to said jacket while simultaneously maintaining said waveguide in said state of tension.
