RG-58 A/U Coaxial Cable

The RG-58 A/U coaxial cable is a high-quality solution for a wide range of applications requiring reliable high-frequency signal transmission. This cable, conforming to the MIL-C-17/029 standard, is ideal for connecting transceiving antennas to radio stations, as well as for use in high-frequency devices, instrumentation, and inter-unit connections in measuring equipment and frequency generators. It is also actively used in the installation of local computer networks, ensuring stable and clean data transmission.

The design of the RG-58 A/U cable is engineered for optimal performance. At its core is a solid central conductor of pure copper with a diameter of 1.0 mm, ensuring minimal signal loss. The dielectric, made of physically foamed polyethylene with a diameter of 2.9 mm, contributes to low capacitance (85.13 pF/m) and a velocity factor of 1.28, which is critically important for high-frequency applications. Dual shielding, consisting of a double-sided aluminum foil on a Mylar base with 100% coverage and a dense tinned copper braid (97% coverage, 16x7x0.12 mm configuration), guarantees an enhanced shielding factor and effective protection against external interference. The outer jacket made of polyvinyl chloride (PVC) with a diameter of 5.0 mm provides durability and flexibility, making the cable very convenient for internal wiring and installation of radio-electronic devices.

Thanks to its low losses across a wide frequency range (e.g., attenuation of 13.4 dB/100m at 150 MHz and 40.6 dB/100m at 1200 MHz) and an impedance of 50±2 Ohms, the RG-58 A/U cable is a versatile choice for critical radio equipment components in VHF/UHF ranges. Its high technical characteristics allow the cable to be used in any climatic conditions. If you are looking for a reliable 50 Ohm coaxial cable, want to buy RG-58 A/U cable for a radio station, or need cable for measuring instruments, this option will exceed your expectations. It is a functional analogue to Belden 7806R, LMR195, and other thin coaxial cables, offering an excellent balance of price and quality. Choose RG-58 A/U for stable connectivity and high performance.

🎁 Expert Advice When installing RG-58 A/U coaxial cable, always try to avoid sharp bends to prevent damage to the dielectric and changes in impedance, which can lead to significant signal loss. Use specialized stripping tools and connectors to ensure a reliable and long-lasting connection.

💡 FAQ What is RG-58 A/U cable used for?
