130. Which of the following coaxial cables is suitable for use in GMDSS MF/HF antenna systems?
GMDSS MF/HF antenna systems require 50-ohm coaxial cable to match the system impedance, minimize signal loss, and prevent equipment damage. Only RG-8, 50 ohm Coax, provides this necessary impedance and is suitable for the required power levels and shipboard installation.
