In hostile climates, the most important feature for coax is protection from the environment. A jacketed coax has a durable outer jacket that seals out moisture, blocks UV exposure, resists temperature extremes, and stands up to abrasion and physical wear. That outer jacket lets outdoor runs, conduit installations, or direct burial survive the harsh conditions without the inner conductors or shielding deteriorating.

Bare aluminum lacks any protective outer layer, so moisture and corrosion can creep in and degrade performance. Copper clad steel provides mechanical strength for pulling but still needs a protective jacket to withstand weather. Fiberglass alone doesn’t offer the same weatherproof, outdoor-ready protection as a jacketed construction. So the jacketed option is the best choice because it delivers the necessary environmental protection for hostile climates.
