Coaxial Cable Engineering: Overcoming Signal Loss in RF Distributions

Coaxial cables are the backbone of Radio Frequency (RF) and television signal distribution systems. At high frequencies, signals attenuate rapidly over long distances, making conductor material choice critical to link performance.

Solid copper (SC) conductors provide the lowest DC resistance and optimal transmission characteristics for broadband and satellite applications. Copper-Clad Aluminum (CCA), while lighter and more cost-effective, exhibits higher resistance. At RF frequencies, due to the skin effect, signal currents travel primarily along the outer copper skin of the CCA conductor, which mitigates some of the losses compared to pure aluminum, but solid copper remains necessary for setups requiring power delivery (such as remote amplifiers). LANKABLE coaxial cables use high-purity solid copper cores and high-density aluminum braiding to ensure maximum shielding efficacy and minimal insertion loss across all RF bands.
