Which type of coaxial cable is recommended for moderate climates?

Bare aluminum coaxial cable is particularly suitable for moderate climates due to its lightweight nature, corrosion resistance, and adequate conductivity. In such climates, where temperature fluctuations are not extreme, the properties of aluminum can be leveraged effectively without the risk of degrading as might be the case in harsher environments, such as those with high humidity or salt exposure.

Copper, while an excellent conductor, is generally heavier and more expensive, making it less ideal for widespread outdoor installations in moderate climates where the benefits of a lighter, more cost-effective option can be realized. Fiber reinforced cable does have its advantages, especially in terms of durability and reduced signal loss, but it is not typically classified under coaxial cables for standard applications. Shielded coax, while providing additional protection against interference, does not possess the necessary attributes for optimal performance in moderate climates compared to bare aluminum options.

Thus, bare aluminum cabling strikes a balance between functionality and cost-efficiency in moderate environmental conditions, making it the preferred choice in this context.
