Advantages of CAVEL RG58 C/U coaxial cable
The CAVEL RG58 C/U cable has several advantages, including:
- High quality from Italian manufacturer CAVEL: Guarantees reliability and durability.
- Compliance with MIL-C-17 standard: Confirms high technical characteristics and suitability for military and critical systems.
- Flexibility due to stranded central conductor: Convenient for installation and use in conditions requiring cable bends.

- Good shielding (93% braid coverage): Provides protection against electromagnetic interference.
Design features and comparison with WL195N
The CAVEL RG58 C/U cable has a stranded tinned copper central conductor, which provides it with high flexibility. The dielectric is solid polyethylene (PE), which has slightly higher signal losses compared to the foamed polyethylene used in the WL195N cable. The RG58 C/U shielding consists of a single tinned copper braid with 93% coverage.
Unlike the RG58 C/U, the CAVEL WL195N cable has a solid central conductor, which makes it more rigid but better for stationary installation and signal transmission at high frequencies with lower losses. The WL195N also features double shielding (aluminum foil and braid), providing better protection against interference. The WL195N's dielectric is foamed polyethylene, which contributes to lower signal attenuation, especially at high frequencies.
Thus, the RG58 C/U is better suited for applications where flexibility and mobility are important, such as connecting car antennas or in amateur radio at frequencies up to 1 GHz. The WL195N is a better choice for stationary systems requiring low signal losses at higher frequencies, such as in Wi-Fi, 4G/5G, and professional radio communications.
