Why Choose RG-223 Instead of RG-58?
RG-223 uses two silver-plated copper braid shields, providing stronger EMI and RFI protection than typical single-braid RG-58 cable. This makes RG-223 an excellent choice for electrically noisy laboratories, equipment racks and professional RF environments.
Frequency Performance
Maximum usable frequency depends on the cable construction, connectors, finished assembly length, connected equipment and acceptable signal loss. Confirm your RF system requirements before ordering.

Yes. This product is a completed 4ft RG-223 BNC male-to-male cable assembly.
Is this a true 50-ohm cable?
Yes. The assembly uses 50-ohm RG-223/U coax and is designed for equipment with compatible 50-ohm BNC connections.
What is the advantage of dual shielding?
The two silver-plated copper braid shields provide excellent protection from electromagnetic and radio-frequency interference.
Can this cable be used for SDI video?
No. Professional SDI video systems require 75-ohm coaxial cable and true 75-ohm BNC connectors. This product is a 50-ohm RF assembly.
