Designed for compatible RF communications, laboratory instrumentation, and test equipment.
Dual-Braid Shielding
Two silver-plated copper braid shields help reduce interference in electrically noisy environments.
Professional BNC Connectors
Precision 50-ohm BNC male connectors provide secure bayonet-style connections.
Hand-Assembled in USA
Each assembly is built by experienced cable technicians and individually tested.
RG-223 Cable Length Guide
| Cable Length | Common Applications |
|---|---|
| 1 Meter / 3 FT | Compact test setups, RF instruments, nearby rack equipment |
| 4–6 FT | Benchtop equipment and short RF interconnections |
| 12–15 FT | Between racks, workstations, and measurement equipment |
| 26–35 FT | Laboratories, equipment rooms, and extended test connections |
| 50 FT | Facility and field connections |
| 100 FT | Longer runs where RF attenuation is acceptable |
Important: RF attenuation increases with cable length and operating frequency. Confirm acceptable insertion loss before selecting longer cables.
RG-223 vs. RG-58 Coaxial Cable
| Feature | RG-223 | RG-58 |
|---|---|---|
| Impedance | 50 Ohm | 50 Ohm |
| Shielding | Dual silver-plated copper braid | Typically single braid |
| Interference Protection | Enhanced shielding | General-purpose shielding |
| Applications | Laboratory, RF, communications | General RF and test systems |
Compare RG-58 50 Ohm BNC Cables
Important: RG-223 Is a 50-Ohm RF Cable
RG-223 assemblies are intended for compatible 50-ohm RF and test equipment. They are not 75-ohm SDI video cables. For professional SDI cameras, switchers, monitors, and video routers, select 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, antennas, radios, and compatible RF equipment.
Laboratory Systems
Research facilities, development laboratories, and electronic test benches.
OEM & Government
Custom assemblies, integration projects, industrial applications, and volume manufacturing.

RG-223 BNC Cable FAQs
What is the difference between RG-223 and RG-58?
RG-223 features dual silver-plated copper braid shielding, offering enhanced interference protection compared with typical single-braid RG-58 coaxial cable.
Is RG-223 a true 50-ohm cable?
Yes. RG-223/U is nominally 50 ohms and is intended for compatible RF equipment and instrumentation.
What is the difference between 1 meter and 3 feet?
One meter equals approximately 3.28 feet, or 39.37 inches. A 3-foot cable measures 36 inches. The 1-meter version provides approximately 3.37 inches of additional length.
Can RG-223 be used for SDI video?
No. Professional SDI video systems use 75-ohm coaxial cable and compatible 75-ohm connectors. RG-223 is intended for 50-ohm RF applications.
How should I select the correct cable length?
Choose the shortest length that safely reaches the equipment. Consider operating frequency, cable routing, and acceptable signal attenuation.
Are custom lengths and quantities available?
Yes. AV-Cables manufactures custom RG-223 assemblies, volume packs, and multi-channel RF cable looms for OEM, government, laboratory, and integration customers.
