Why Choose RG-223 Coaxial Cable?
RG-223/U is a professional 50-ohm coaxial cable with two silver-plated copper braid shields. This dual-shield construction provides stronger EMI and RFI protection than typical single-braid RG-58 cable, making RG-223 a strong choice near computers, power supplies, transmitters and other electronic equipment.
True 50-Ohm Construction Designed for compatible RF, communications and electronic test equipment.
Dual-Braid Shielding Two silver-plated copper braid shields provide strong interference rejection.
Professional BNC Connections BNC male connectors provide secure bayonet connections to compatible equipment.
RG-223 Length Guide
| Length | Common Applications |
|---|---|
| 3–6 ft | Nearby rack equipment, benchtop instruments, test systems and compact RF interconnects |
| 15 ft | Connections across work areas, between racks and to remotely positioned devices |
| 26–30 ft | Equipment rooms, laboratories, antenna systems and extended measurement connections |
| 50 ft | Facility, field and equipment-room connections requiring additional reach |
| 100 ft | Long facility and field connections after verifying acceptable loss for the operating frequency |
RG-223 vs. RG-58 Coaxial Cable
| Feature | RG-223 | Belden 9201 RG-58 |
|---|---|---|
| Application Impedance | 50 ohms | Designed for standard 50-ohm systems |
| Shielding | Dual silver-plated copper braid | Single bare-copper braid |
| Best Use | Demanding RF, laboratory and electrically noisy environments | General-purpose 50-ohm RF and test applications |
RG-223 Is a 50-Ohm RF Cable
These RG-223 assemblies are intended for compatible 50-ohm RF, communications and test equipment. They are not 75-ohm SDI video cables. For cameras, switchers, monitors and video routers, choose a true 75-ohm SDI BNC cable.
Common RG-223 Applications
Test & Measurement Oscilloscopes, signal generators, spectrum analyzers and network analyzers.
RF Communications Receivers, transmitters, radios and compatible communications equipment.
Laboratory Systems Bench instruments, equipment racks and research or development systems.
Integration & OEM Government, military, industrial, integration and volume-production requirements.

RG-223 BNC Cable FAQs
What is the advantage of RG-223 over RG-58?RG-223 uses dual silver-plated copper braid shielding, providing stronger EMI and RFI protection than typical single-braid RG-58 construction.
Is RG-223 a true 50-ohm cable?Yes. RG-223/U is a nominal 50-ohm coaxial cable intended for compatible RF, communications and test equipment.
Can RG-223 be used for SDI video?No. Professional SDI video systems require 75-ohm coaxial cable and true 75-ohm BNC connectors.
How should I choose the cable length?Choose the shortest length that safely reaches the equipment. Confirm acceptable signal loss for the system’s operating frequency, especially on longer runs.
Are custom lengths and quantities available?Yes. Contact AV-Cables for custom assemblies, volume production, multicore looms and OEM requirements.
