Utilising Copper Tubing as an outer conductor and shielding layer on Semi-Rigid RF cable types presents both advantages and potential drawbacks. On the positive side, Copper Tube offers excellent electrical conductivity, which is crucial for minimising signal loss. Its smooth surface also reduces skin effect, enhancing the cable's overall performance. Copper's natural resistance to corrosion ensures the longevity of the cable, reducing maintenance and replacement costs over time. Copper is a relatively soft metal, which allows its forming into a desired shape, however lack of care when forming may compromise the cable's physical durability through bending and deformation, which could negatively impact signal integrity.
