Abstract

A quad-shield coaxial cable includes an insulator portion configured to encircle an inner conductor portion, an inner conductive foil portion configured to encircle the insulator portion, an inner braided shield portion configured to encircle the inner conductive foil layer portion, an outer braided shield portion configured to encircle the inner braided shield portion, an outer conductive foil portion configured to encircle the outer braided shield portion, and a jacket portion configured to encircle the outer conductive foil portion.

Claims

1. A quad-shield coaxial cable comprising:

an insulator portion configured to encircle an inner conductor portion;

an inner conductive foil portion configured to encircle the insulator portion;

an inner braided shield portion configured to encircle the inner conductive foil layer portion;

an outer braided shield portion configured to encircle the inner braided shield portion;

an outer conductive foil portion configured to encircle the outer braided shield portion; and

a jacket portion configured to encircle the outer conductive foil portion.

2. The cable of claim 1, wherein the inner conductor portion comprises an elongated center conductor that extends along a longitudinal axis.

3. The cable of claim 2, wherein the inner conductive foil portion comprises an inner conductive foil layer that coaxially surrounds the insulator portion.

4. The cable of claim 3, wherein the inner braided shield portion comprises an inner layer of braided shield that coaxially surrounds the inner conductive foil layer.

5. The cable of claim 4, wherein the outer braided shield portion comprises an outer layer of braided shield that coaxially surrounds the inner layer of braided shield.

6. The cable of claim 5, wherein the outer conductive foil portion comprises an outer conductive foil layer that coaxially surrounds the outer layer of braided shield.
