💬 Comment / comments
The SLL-400-FPG features a stranded copper center conductor, triple-layer high-pressure foamed polyethylene dielectric, and double shielding with copper foil and dense braid. This construction delivers excellent interference protection and low attenuation at high frequencies. The cable is UV-resistant, mechanically robust, and well-suited for tower, mast, and outdoor RF installations. It is often chosen as a cost-effective alternative to LMR-400 in professional RF infrastructures.
