Description
RG-55 is a high-quality, flexible coaxial cable designed for high-frequency 50 Ohm systems. It is widely regarded as a premium upgrade to the standard RG-58, distinguished primarily by its double-braided shielding. This dual-layer shield—typically consisting of two layers of silver-plated or tinned copper braid—provides exceptional isolation and significantly reduces RF leakage, making it ideal for sensitive test equipment and tactical communications.
The cable features a solid or stranded 20 AWG silver-plated copper-clad steel (SPCCS) center conductor, which ensures excellent conductivity and high tensile strength. The silver plating enhances high-frequency performance by utilizing the “skin effect” to minimize resistance. Surrounded by a solid polyethylene (PE) dielectric and protected by a non-contaminating or UV-resistant jacket, RG-55 is built to maintain tight electrical tolerances even in harsh operational environments. It is commonly terminated with SMA, TNC, or N-Type connectors.
Key Technical Advantages
-
Superior Double Shielding: The two-layer braided shield provides much higher attenuation of external interference and lower signal egress compared to single-shielded cables.
-
Silver-Plated Conductor: Enhances electrical conductivity at microwave frequencies and provides excellent corrosion resistance for long-term reliability.
-
High Signal Integrity: Precision manufacturing ensures a very low VSWR and consistent impedance, which is critical for accurate measurements in laboratory settings.
-
Rugged and Flexible: Despite its heavy-duty shielding, the cable remains flexible enough for easy routing in tight chassis or mobile communication rigs.
-
Environmental Stability: Built with materials that resist moisture, chemicals, and UV exposure, making it suitable for aerospace and outdoor tactical use.

Really worth the price and the product quality is excellent. Packaging was secure and delivery was on time. Much better option for Indian customers instead of importing from outside India. Thank you AetherX!
