Among coaxial cables, those that have harsh environment durability include RG-6 (television and cable internet, jacket resistant to UV radiation), RG-58 (RF application, flexible), as well as low loss coaxial types like LMR-400 which is foam dielectrically filled and low loss premium alternatives. Added shielding moisture and gap shielding can be provided with constructions of braided aluminum and copper. For long life expectancies, select cables with Temperature ratings IP67 (outdoors) and certifications (-55°C to +85°C).
