1. A coaxial cable comprising:
- a center conductor;
a first precoat layer surrounding and adjacent to the center conductor, the first precoat layer configured to prevent moisture located circumferentially outward to the first precoat layer from contacting the center conductor;
a second precoat layer surrounding and adjacent to the first precoat layer, the second precoat layer configured to prevent moisture located circumferentially outwardly to the second precoat layer from contacting the first precoat layer; and
a dielectric surrounding and adjacent to the second precoat layer.

Abstract
Disclosed herein is a coaxial cable that includes a center conductor and a first precoat layer surrounding and adjacent to the center conductor. The first precoat layer is configured to prevent moisture located circumferentially outward to the first precoat layer from contacting the center conductor. The coaxial cable includes a second precoat layer surrounding and adjacent to the first precoat layer. The second precoat layer is configured to prevent moisture located circumferentially outwardly to the second precoat layer from contacting the first precoat layer. The coaxial cable further includes a dielectric surrounding and adjacent to the second precoat layer.

20. A coaxial cable comprising:
-
a center conductor; a first precoat layer surrounding and adjacent to the center conductor; a second precoat layer surrounding the first precoat layer; and a dielectric surrounding and adjacent to the second precoat layer; wherein the first precoat layer is configured to bond to the center conductor and the second precoat layer is configured to bond to the dielectric, and wherein the second precoat layer forms a stronger bond with the dielectric than the first precoat layer forms with the center conductor.
