Abstract
A coaxial cable has a return loss higher than 36 dB and a structural return loss higher than 38 dB within the frequency range from 500 to 1000 MHz. The coaxial cable has a polyolefin inner solid insulating layer having an adhesive strength of between 40 and 60 lb/in2 to a central conductor, an intermediate foamed polyolefin layer surrounding the polyolefin inner solid insulating layer, an outer polyolefin solid insulating layer surrounding the intermediate foamed polyolefin layer, a metallic screen layer that has of a shield made of a metallic foil and a braid surrounding the outer polyolefin solid insulation layer, and a protective jacket surrounding the metallic screen layer.
Claims4
A coaxial cable having a return loss higher than 36 dB and a structural return loss higher than 38 dB within the frequency range from 500 to 1000 MHz, the coaxial cable comprising:
- a central conductor;
- an inner polyolefin solid insulating layer surrounding said central conductor and being adhered to said central conductor in an amount of between 40 and 60 lb/in2;
- an intermediate foamed polyolefin insulating layer surrounding a surface of said inner polyolefin solid insulating layer opposite said central conductor;
- an outer polyolefin solid insulating layer surrounding a surface of said intermediate foamed polyolefin insulating layer opposite said inner polyolefin solid insulating layer;
- a metallic screen layer being a shield of a metallic foil and a braid, said metallic screen layer surrounding a surface of said polyolefin solid insulating layer opposite said intermediate foamed polyolefin insulating layer;
- and
- a protective jacket surrounding a surface of said metallic screen layer opposite said outer polyolefin solid insulating layer.
