Detailed description
Detailed description
Designed for marine radio-frequency (RF) applications, the AC ANTENNAS RG58CU 20 m coaxial cable is a flexible 50 Ω cable compliant with MIL-C-17F specifications. It is suitable for various VHF and AIS antenna installations, ensuring reliable signal transmission. Its robust construction and electrical specifications make it compatible with equipment such as 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 is provided by a tinned-copper braid, offering high 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 Ω, 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. Compliance with MIL-C-17F standard confirms its robustness and reliability in demanding environments. The cable is suitable for frequencies up to 3 GHz.
