What are RG23 Coaxial Cables?

RG23 coaxial cables are a type of cable that has been designed for high frequency signal transmission. These cables offer high signal integrity and low loss of transmission, making them suitable for long distance transmission applications.

RG-23/A/U

The RG-23/A/U is a 125-ohm coaxial cable with an overall diameter of 0.650 inches and has a voltage rating of up to 3000 Vrms. It consists of two individually coated bare copper conductors with 7-stranding construction (carrying the electrical signal). The inner conductors are enclosed by an insulation layer typically made of Polyethylene (PE). The insulation layer is then completely enclosed by two shield layers made of bare copper braid. The shields form an outer conductor and also offer protection against electromagnetic interference (EMI). Finally, the structure is covered with an outermost layer called a jacket made of Polyvinyl Chloride (PVC). The jacket protects the cable core from mechanical, moisture, and chemical issues.  

The RG-23/A/U cable exhibits an approximate capacitance of 12 to 13 pF/ft and has signal attenuation of around 5.2 dB/100 ft at 400 MHz (signal attenuation of the cable depends on the frequency).
