RG223 Coaxial Cable – Specifications, Features & Applications Guide

Introduction

RG223 coaxial wire is a high-performance 50-ohm coaxial cable designed for dependable RF signal transmission in harsh situations. It is widely utilized in telecommunications, military systems, radio communication, and test and measurement applications due to its double shielding and low signal loss properties.

Compared to normal RG58 cable, RG223 has a higher shielding efficacy, making it suited for locations with strong electromagnetic interference.

What is RG223 Coaxial Cable ?

RG223 is a 50-ohm impedance coaxial cable, featuring:

• Silver-plated copper conductor.

• PTFE (Teflon) dielectric insulation.

• Double-braided silver-plated copper shielding

• Durable outer jacket (in PVC or FEP variants)

• Its double shield design enhances EMI protection and signal integrity in high-frequency systems.

Types of RG 223 Coaxial Cable :

RG223 cable is available in a variety of configurations depending on jacket material and application needs.

1. Standard RG 223 (PVC Jacket)

• Flexible and cost-effective.

• Ideal for indoor installations.

• Common in communication systems.

2. RG223 with FEP Jacket

• Higher temperature resistance.

• Improved chemical and UV resistance

• Used in the aerospace and extreme settings.

3. Low smoke, zero halogen (LSZH) RG223

• Reduced toxic emissions in case of fire

• Ideal for enclosed public spaces.

4. Pre-assembled RG223 Cable Assemblies

• Factory-terminated with connections.

• Available in SMA, BNC, TNC, or N-type connectors.
