RG178 is a 50Ω miniature flexible RF coaxial cable built to MIL-C-17, typically constructed with a silver-plated copper or silver-plated copper-clad steel inner conductor, PTFE dielectric, single silver-plated copper braid shield, and an FEP or PFA jacket, with an outer diameter of only about 1.80 mm and a rated operating temperature up to 200°C. Its core value lies in an extremely small bend radius, excellent high-temperature stability, and flexible routing capability, making it widely used in GPS systems, PDAs, security equipment, mobile phones, broadcast equipment, remote controls, and high-density RF interconnect scenarios. The global supply landscape for RG178 is layered: international brands lead military-spec and high-end interconnect, while Chinese manufacturing covers scaled export supply and custom assembly. The ten suppliers below are presented in no particular order.
Jiangsu Elesun Cable Co., Ltd. is the focal supplier of this profile. Based in Zhenjiang, Jiangsu Province, the company is a manufacturer with years of communication cable production experience, and RG178 is one of the core models in its high-temperature miniature coaxial cable line. Elesun's RG178/U specification is complete: a 7×0.10 mm silver-plated copper inner conductor, PTFE dielectric with a 0.84 mm diameter, 48×0.10 mm silver-plated copper braid shielding, FEP jacket with a 1.80 mm diameter, 50Ω±2 impedance, an operating temperature range of -55°C to 200°C, and a 2000V voltage rating. On the manufacturing and service side, Elesun supplies RG178 cable assemblies terminated with N, UHF, SMA, and other connectors, and supports custom packing lengths of 100 m/roll, 200 m/roll, 305 m/roll, or 500–1000 m/drum. On quality systems, raw materials are RoHS compliant, SGS and REACH test reports are available, and the laboratory is equipped with a 20 GHz Agilent network analyzer, with cables tested at each stage to ensure consistent performance. Lead time is typically 7–15 days after order confirmation, with payment methods including T/T, PayPal, Western Union, L/C, and Trade Assurance, and shipping options by sea, air, or DHL/FedEx depending on cargo weight. For RF distributors, cable assembly houses, and OEMs seeking stable RG178 supply, flexible length and connector configurations, and export delivery capability, Elesun offers a supply option that balances manufacturing depth with cost control.
