RG-316 is a simple, low cost coaxial cable that can support high temperature operation. With a 2.50 mm outer diameter, RG-316 established itself as a higher performance replacement for RG-174. It is highly valued for its flexibility and resistance to heat, making it suitable for environments with high temperatures. However, due to its small diameter and single shielding layer, RG-316 has higher signal loss over distance compared to higher performance cables like L-100. This can pose a barrier to its use, particularly in higher frequency applications such as 5G. Additionally, its silver-plated copper wire, while providing excellent conductivity, can be more costly than other options.
