Choose Your RG-58 BNC Cable

Select the shortest cable length that comfortably reaches your equipment. Shorter RF cable runs generally provide lower signal loss, especially as operating frequency increases.

Short RF Interconnects

Ideal for equipment racks, benchtop instruments and closely positioned RF devices.

1.5–10 ft

Equipment & Rack Runs

Useful for communications equipment, wireless systems and larger equipment racks.

15–35 ft

Longer RF Runs

Available when greater distance is required. Always consider frequency-dependent signal loss when selecting longer RF cable runs.

50–100 ft

Common RG-58 50-Ohm Applications

RF Communications
Professional radio and communications equipment
Test Equipment
Oscilloscopes, signal generators and compatible instruments
Wireless Systems
Compatible antenna and RF distribution applications
Laboratory Systems
Benchtop and professional RF equipment interconnects

RG-58 vs. RG-223 vs. 75-Ohm BNC

Selecting the correct impedance and cable construction is important. RG-58 and RG-223 are commonly used with 50-ohm RF equipment, while professional SDI video systems require 75-ohm coaxial cable.

Cable Type Impedance Best For Typical Use
RG-58 / Belden 9201 50 Ohm General-purpose RF Communications, wireless and test equipment
RG-223 50 Ohm Enhanced shielding Laboratory, RF and electrically noisy environments
SDI Coax 75 Ohm Professional digital video Cameras, switchers, monitors and video routers

Important: RG-58 Is a 50-Ohm Cable

RG-58 cable is intended for compatible 50-ohm RF and communications equipment. It should not be substituted for a 75-ohm BNC cable in professional SDI video systems. For cameras, switchers, monitors, converters and video routers, choose a 75-ohm SDI BNC cable.

Should I Choose RG-58 or RG-223?

Choose Belden 9201 RG-58 for general-purpose 50-ohm RF, communications and test-equipment connections where a flexible, professional coaxial cable is required.

Choose RG-223 when additional shielding is important. RG-223 uses dual braid shielding and is well suited to demanding RF, laboratory and electrically noisy environments.

Need Multiple 50-Ohm BNC Channels?

AV-Cables also manufactures custom multi-channel 50-ohm BNC cable assemblies for RF racks, wireless systems, laboratories and professional installations.

Choose from RG-58 or RG-223 constructions with multiple individually shielded and identified BNC channels organized into a single professional cable loom.

RG-58 BNC Cable FAQs

Is RG-58 a 50-ohm or 75-ohm cable?

RG-58 is a 50-ohm coaxial cable commonly used for RF, communications, wireless and test-equipment applications.

Can RG-58 be used for SDI video?

RG-58 should not be used as a replacement for the 75-ohm coaxial cable specified for professional SDI video systems.

What is the difference between RG-58 and RG-223?

Both are 50-ohm coaxial cable types, but RG-223 provides enhanced shielding with a dual-braid construction. RG-58 is an excellent choice for many general-purpose RF applications, while RG-223 is useful where additional EMI/RFI shielding is desirable.

Does cable length matter with RF signals?

Yes. Signal attenuation increases with cable length and frequency. Use the shortest practical cable and confirm the loss requirements of your RF system when working at higher frequencies or over longer distances.

Need a Custom 50-Ohm BNC Assembly?

AV-Cables manufactures custom RF cable assemblies for professional communications, wireless, laboratory and equipment-rack applications.

Custom lengths, RG-58, RG-223 and multi-channel configurations are available.
