In hostile climates, the outer protective layer of coax is essential to keep moisture, temperature changes, UV exposure, and physical damage from compromising the signal. The jacketed coax has that protective outer sheath, usually a weather- and moisture-resistant jacket such as PVC or polyethylene, making it suitable for outdoor or harsh environments. Bare aluminum lacks any outer protection, so corrosion and moisture intrusion would quickly become an issue. Copper clad steel is a strong conductor option, but it still needs a jacket to withstand outdoor conditions; without protection, it wouldn’t endure harsh climates. Foamed polyethylene is the insulation inside the cable, not the protective outer layer, so it doesn’t address environmental exposure. Therefore, jacketed coax best fits hostile climates.
