What are RG114 Coaxial Cables?

RG114 Coaxial Cables are a type of cable that is commonly used for telecommunications and networking applications. These cables are ideal for carrying radio frequency (RF) signals over longer distances due to their lower signal attenuation and high degree of signal integrity.

RG-114/A/U

The RG114/U is a 185-ohm coaxial cable with an overall diameter of 0.405 inches and has a voltage rating of up to 1000 Vrms. It has an internal copper weld wire (CW) or copper-clad steel (CCS) conductor (carrying the electrical signal), which is enclosed by an insulation layer made of air space Polyethylene (ASP). The insulation layer is then completely enclosed by 1 bare copper braid shield that forms the outer conductor and also provides shielding 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 RG114/A/U cable exhibits capacitance of approximately 7 pF/ft (23.02 pF/m), and signal attenuation of around 8.5 dB/100 ft at 400 MHz (signal attenuation of the cable depends on the frequency). It has a center conductor measuring 0.0070 inches (0.1778 mm) in diameter and an insulation layer measuring 0.285 inches (7.2 mm) in diameter.
