5. The axial cable of claim 1 , wherein the second conductor contactor comprises a deformable member.
6. The axial cable of claim 1 , wherein the second conductor contactor is substantially cylindrical.
7. The axial cable of claim 1 , wherein the axial cable has a length, and wherein the axial cable has a substantially constant impedance along the length.
8. The axial cable of claim 1 , wherein the second conductor contactor is removable.
9. The axial cable of claim 1 , wherein the receiving structure comprises a center conductor mating surface and an outer conductor mating surface, and wherein the second conductor contactor end is positioned to contact the outer conductor mating surface on the receiving structure prior to the first conductor contacting the center conductor mating surface on the receiving structure.
10. The axial cable of claim 9 , wherein the second conductor contactor is configured to flex in response to contacting the receiving structure and wherein the second conductor contactor is adapted to scrape at least a portion of the outer conductor mating surface in response to flexing.
11. The axial cable of claim 1 , wherein the second conductor contactor comprises at least one of: (a) helical structure; (b) a coil structure; (c) a twisting structure; (d) a spiral structure; (e) a crown structure; (f) a lattice structure; or (g) a multi-fingered structure.
12. The axial cable of claim 1 , wherein the second conductor contactor is adapted to scrape at least a portion of the receiving structure in response to contacting the receiving structure.
13. The axial cable of claim 1 , wherein the second conductor contactor end comprises at least one of: (a) substantially straight bendable structures; (b) curved bendable structures; or (c) bent deflectable structures.
14. The axial cable of claim 1 , wherein the second conductor contactor comprises at least one of (a) a deformable portion; or (2) a deflectable portion.
15. The axial cable of claim 1 , wherein the second conductor contactor comprises deformable portions having attached ends.
16. The axial cable of claim 15 , wherein a contact surface of the attached ends of the deformable portions comprises a scraping surface.
17. The axial cable of claim 1 , further comprising a biasing member and a limiter about the second conductor.
18. The axial cable of claim 1 , wherein the second conductor contactor comprises a compliant ferrule, and wherein the first conductor further comprises an extension tip.
19. The axial cable of claim 1 , further comprising a support shield about a compliant portion of the second conductor contactor.
20. The axial cable of claim 1 , wherein the second conductor contactor end comprises at least one of: (a) substantially straight structures; (b) curved structures; or (c) bent structures.
21. The axial cable of claim 1 , wherein the second conductor contactor defines a substantially cylindrical shape; and
wherein the second conductor contactor comprises deformable portions having attached ends, the deformable portions configured to retain the substantially cylindrical shape of the second conductor contactor when deforming upon engagement of the axial cable with the receiving structure.
22. The axial cable of claim 21 , wherein a contact surface of the attached ends of the deformable portions comprises a scraping surface.
23. The axial cable of claim 1 , wherein the second, conductor contactor comprises a plurality of deformable members arranged, in combination, substantially in a circle having a diameter, and wherein the diameter remains substantially unchanged upon deformation of the deformable members upon engagement of the axial cable with the receiving structure.
24. The axial cable of claim 23 , wherein a substantially uniform spacing is maintained between the first conductor and the second conductor along a length of the first conductor.
