Description

What is RG58 cable?

RG58 is a coaxial cable commonly used for radio frequency (RF) communications, low-power signal transmission, and data applications. It has a characteristic impedance of 50 ohms, making it suitable for applications such as:

RF Communications: Connects CB radios, ham radios, and RF transmitters.
Antenna Connections: Links antennas to radio equipment.
Networking (Legacy): Used in older 10BASE2 Ethernet (Thinnet) networks.
Test Equipment: Connects oscilloscopes, signal generators, and other lab devices.
Surveillance Systems: Sometimes used for analog CCTV setups.

RG58 typically consists of a stranded or solid center conductor, a dielectric insulator, a shielding layer (braid or foil), and an outer protective jacket. It is flexible and relatively low-cost but has higher signal loss compared to thicker coaxial cables like RG8.

What is CCS RG58 cable？

CCS RG58 refers to RG58 coaxial cable with a Copper-Clad Steel (CCS) center conductor. This means the core is made of steel with a thin layer of copper.

Characteristics of CCS RG58:

Higher Strength: More durable and resistant to breaking.
Lower Cost: Cheaper than solid copper versions.
Higher Signal Loss: Higher resistance than pure copper, leading to more attenuation, especially at high frequencies.
Still Supports RF Applications: Suitable for applications where flexibility and low cost are prioritized over minimal signal loss.

Best Uses:

Short-distance RF communication (CB radios, antennas).
Cost-sensitive applications where minimal power loss is acceptable.
General-purpose signal transmission with moderate performance needs.

For applications requiring better conductivity and lower loss, pure copper RG58 (BC or SCC) is preferred.

The difference between CCS RG58 and copper RG58 cable

The main difference between CCS RG58 (Copper-Clad Steel) and Copper RG58 lies in the conductor material, affecting electrical performance and cost

Feature	CCS RG58 (Copper-Clad Steel)	Copper RG58 (Bare Copper - BC)
Center Conductor	Steel core with a thin copper coating	Pure copper
Conductivity	Lower (higher resistance)	Higher (better signal transmission)
Signal Loss	Higher attenuation, especially at high frequencies	Lower attenuation, better performance
Strength & Durability	More rigid and durable	More flexible but less strong
Cost	Cheaper	More expensive
Best For	Short cable runs, budget applications	High-performance RF, low-loss applications

Which One to Choose?

Use CCS RG58 for cost-sensitive applications where some signal loss is acceptable (e.g., CB radios, general RF use).
Use Copper RG58 when better signal quality and lower loss are needed (e.g., longer cable runs, sensitive RF applications).

custom RG58 cable and custom Semi-finished coaxial RG cable

Custom RG58 Cable:

Made to specific lengths, connectors, and shielding types based on user needs.
Can include pure copper or CCS conductor, different jacket materials (PVC, LSZH, etc.), and custom impedance matching.
Used for RF applications, antennas, network setups, and lab equipment.

Custom Semi-Finished Coaxial Cable:

Partially manufactured coaxial cables, allowing customization before final assembly.
Comes with unfinished ends, allowing users to add their own connectors, shielding, or jacket.
Ideal for manufacturers, integrators, and projects requiring specific performance tuning.
