50 Ohm RF coaxial cable, RG58CU, 20m, black, MIL-C-17F

Designed for marine radio frequency (RF) applications, the AC ANTENNAS RG58CU coaxial cable (20 meters) is a flexible 50 Ohm cable compliant with MIL-C-17F specifications. It is suitable for various VHF, AIS, and satellite compass antenna installations, ensuring reliable signal transmission. Its robust construction and electrical specifications make it compatible with equipment such as the Furuno SC-30 satellite compass or the Furuno FA-30 AIS receiver.

Construction and Technical Specifications

This RG58CU coaxial cable features a stranded tinned copper inner conductor, typically composed of 19 strands of 0.18 mm, for optimal flexibility and conductivity. The dielectric insulation is solid polyethylene (PE) with a diameter of approximately 2.95 mm. The shielding consists of a tinned copper braid, providing significant coverage (approximately 91% to 96%) to minimize RF interference. The outer black PVC jacket has a diameter of approximately 4.95 mm to 5.0 mm.

Performance and Compliance

With a nominal impedance of 50 ± 3 Ohm, this cable has a capacitance of approximately 98-101 pF/m and a propagation velocity of approximately 66%. It is designed for a maximum voltage of 1900 Vrms and can operate within a temperature range of -40°C to +85°C. Its compliance with MIL-C-17F attests to its robustness and reliability in demanding environments. The cable is suitable for frequencies up to 3 GHz.
