Joints, the latter being pressed (Cl. 173-285) v 2. A flexible radio frequency line comprising inner and outer conductors spaced concentrically apart by insulated rings having "their outer periphery rounded over to form an element of a ball joint, said outer conductor consisting of a 5 plurality oi semi-cylindrical tubular links of relatively short length, each of said links having their ends formed to engage the end 01' another similar tubular link, and each of said link ends shaped to engage the outer periphery of said in- 10 sulated rings, each of said links Joined by a plurality of metallic rings which are bent to conform with the ends oi said links.
3. A flexible radio frequency line comprising inner and outer conductors spaced concentrically l6 apart by a plurality of insulators having their outer periphery rounded over to form an element of a ball joint, said outer conductor consisting of a plurality of semi-cylindrical tubular links of relatively short length, each of said links having their ends .iormed to engage the end of another similar tubular link, and each of said link ends shaped to engage the outer periphery of said insulated rings, each 01' said links Joined by aplurality of metallic rings which are bent to conform with the ends of said links, said outer conductors and said metallic rings being completely covered by a spiral winding oi a band of metallic tape.
4. A flexible radio frequency line comprising inner and outer conductors spaced concentrically apart by insulated rings having their outer periphery rounded over to form an element of a ball Joint, said outer'conductor consisting of a plurality oi semi-cylindrical tubular links oi relatively short length, each of said links having their ends formed to engage the end 01' another similar tubular link, each of said link ends shaped to engage the outer periphery of said insulated rings, each or said links Joined by a plurality oi metallic rings which are bent to conform with the ends 40 of said links, and said outer conductor having its inside provided with a lead sheath to insure air and water tight seal.
5. A flexible radio frequency line comprising inner and outer conductors, said outer conductor comprising a plurality oi split tubular links which are joined by insulated ball joints and a covering of copper toil spirally wrapped around said outer conductor.
