COAX (P/N rg58) - New Surplus

The RG-58 is a 50-ohm coaxial cable designed for RF signal transmission in aircraft avionics systems. This shielded cable connects VHF communication radios to external antennas, maintaining signal integrity across transmission lines. Constructed to MIL-C-17 specifications for general-purpose utility service, the RG-58 features a center conductor, dielectric insulation, braided shield, and outer jacket that protect against electromagnetic interference.

Proper routing, support, and termination per FAA AC 43.13 preserve impedance characteristics and minimize signal loss during installation and operation.
