FAQ

Questions engineers ask first

Do RG-213 connectors fit RG-214?

While both cables share a 7.24 mm (0.285 in) dielectric diameter and 2.26 mm center conductor, RG-214's second silver-plated braid increases its outer diameter from 10.30 mm (0.405 in) to 10.80 mm (0.425 in), so you should specify Type N, TNC, or BNC connectors sized specifically for RG-214/RG-9.

Why does RG-214 use silver-plated copper when RG-213 uses bare copper?

Above 1 GHz, all RF current flows within the outer few micrometres of the conductor and shield (skin effect); silver has the highest conductivity of any metal and its oxide remains conductive, giving RG-214 stable microwave performance up to 11 GHz. Each production reel undergoes sweep-frequency impedance and return-loss verification, dielectric spark testing, and dimensional inspection before dispatch with an EN 10204 3.1 test certificate.

How much additional RF isolation does RG-214 provide over RG-213?

Single-braided RG-213 offers approximately 55–60 dB of shielding effectiveness, whereas RG-214's counter-woven dual silver-plated copper braids achieve > 90 dB isolation—a > 1,000× reduction in leaked RF power. Each production reel undergoes sweep-frequency impedance and return-loss verification, dielectric spark testing, and dimensional inspection before dispatch with an EN 10204 3.1 test certificate.

Is a halogen-free shipboard version of RG-214 available?

Yes, RG-214-LSZH replaces the PVC Type IIA jacket with a flame-retardant low-smoke zero-halogen (LSZH) compound for naval vessels, submarines, and underground tunnels. Each production reel undergoes sweep-frequency impedance and return-loss verification, dielectric spark testing, and dimensional inspection before dispatch with an EN 10204 3.1 test certificate.
