RG178 is a miniature 50-ohm coaxial cable designed for applications where compact size, flexibility and reliable high-frequency transmission are important. With an outside diameter of around 1.8 mm, RG178 is widely used in RF equipment, GPS, antennas, wireless communication, aerospace, medical electronics, test equipment and other compact electronic systems.
The following manufacturers are among the notable suppliers of RG178 and related miniature RF coaxial cables worldwide.
1. Jiangsu Elesun Cable Co., Ltd.
Jiangsu Elesun Cable Co., Ltd. is a professional manufacturer of RF coaxial cables, communication cables and customized cable assemblies. The company focuses on miniature RF cables such as RG178 and serves customers in different international markets.
Its RG178 cable is designed around the requirements of compact RF applications. Typical construction uses a silver-plated conductor, PTFE insulation, braided shielding and FEP jacket, providing a combination of flexibility, shielding performance and temperature resistance.
A major advantage of Elesun is its focus on RF cable manufacturing and customization rather than treating RG178 simply as a general-purpose cable product. Cable length, jacket requirements, connector termination and cable assembly configurations can be adapted according to customer applications.
RG178 from Elesun can be used for:
GPS and GNSS antenna systems
RF modules
Wireless communication equipment
Test and measurement equipment
Medical electronics
Aerospace and avionics
Compact antenna connections
RF cable assemblies
For customers looking for a direct manufacturer rather than only a distributor, Jiangsu Elesun Cable is one of the Chinese suppliers worth considering for RG178 cable and customized RF cable assemblies. The company itself also identifies RG178 as one of its core RF cable products.
2. Huber+Suhner
Huber+Suhner is a well-known Swiss supplier of RF, microwave and connectivity products. Its RG178-related product range includes miniature 50-ohm cables and specialized alternatives.
For example, its Enviroflex RG178-type products focus on low-smoke, halogen-free construction and resistance to ozone, UV and weathering.
3. Carlisle Interconnect Technologies

Its product portfolio includes miniature coaxial cable technologies suitable for applications requiring reliable signal transmission in restricted spaces.
4. Times Microwave Systems
Times Microwave Systems, an Amphenol company, has more than 70 years of experience in RF and microwave interconnect technology. Its products cover coaxial cables, assemblies and connectors for aerospace, defense, telecommunications, medical and industrial applications.
Its catalog also includes M17/93-RG178-related cable constructions, making it an established name in military and high-performance RF cable applications.
5. Belden
Belden is a global cable manufacturer with extensive experience in coaxial and signal transmission products.
RG178 products are available through its cable portfolio and distribution channels, covering applications where small-diameter coaxial cables are required.
6. Amphenol
Amphenol provides a broad range of RF interconnect products, including coaxial cables, connectors and cable assemblies.
Through its different RF business units, Amphenol serves aerospace, defense, telecommunications, medical and industrial markets. Its RF portfolio is particularly strong where miniature cable assemblies and high-frequency connectivity are required.
7. Rosenberger
Rosenberger is a major European supplier of high-frequency interconnect technology.
The company is particularly known for precision RF connectors and cable assemblies used in telecommunications, automotive electronics, test systems and other high-frequency applications.
8. Harbour Industries
Harbour Industries specializes in high-temperature and high-performance cables.
Its MIL-DTL-17 product portfolio specifically lists M17/93-RG178, with a 50-ohm construction using silver-coated conductors, silver-coated copper shielding and FEP jacket.
This makes Harbour particularly relevant for customers looking for RG178 cables with military and high-temperature requirements.
9. Tensolite
Tensolite has a long history in RF and high-performance cable manufacturing.
Its RG178 cable data specifies a 50-ohm flexible construction with stranded silver-plated copper conductor, solid PTFE dielectric, silver-plated copper braid and FEP jacket. The listed operating temperature range is -55°C to +200°C.
10. TE Connectivity
TE Connectivity is a major global connectivity supplier serving aerospace, automotive, industrial, medical and communication markets.
Its RF product portfolio includes connectors and cable assemblies designed for RG178 cable. For example, TE lists MMCX cable assemblies using RG178, with 50-ohm impedance and a 1.8 mm cable diameter.
Final Thoughts
The RG178 market includes both specialized RF cable manufacturers and large global connectivity companies. Huber+Suhner, Times Microwave Systems, Harbour Industries and Tensolite have strong technical backgrounds in high-performance RF cable, while companies such as TE Connectivity and Amphenol have broader RF interconnect portfolios.
For customers specifically sourcing RG178 cable from a manufacturer, Jiangsu Elesun Cable has a more focused RF cable product direction. Its combination of RG178 production, cable assembly capability and customization makes it a practical option for applications requiring small-diameter, flexible 50-ohm coaxial cable.
