What are RG403 Coaxial Cables?

RG403 Coaxial Cables are a type of cable that has been designed to offer robustness and high signal integrity with a lower level of signal attenuation. This makes them ideal for underground cabling purposes for wireless and telecommunication applications.

RG403/U

RG403/U Cable ConstructionThe RG403/U is a 50-ohm coaxial cable with an overall diameter of 0.116 inches and a voltage rating of up to 1000 Vrms. It has an internal silver-covered copper conductor with a 7-stranding construction (carrying the electrical signal), which is enclosed by an insulation layer made of Polytetrafluoroethylene (PTFE). The insulation layer is then completely enclosed by 2 silver-covered copper braid shields that form the outer conductor and also provide shielding against electromagnetic interference (EMI). ). Finally, the structure is covered with an outermost layer - called a jacket - made of Fluorinated ethylene propylene (FEP-IX) & Fluorinated Ethylene Propylene (FEP). The jacket protects the cable core from mechanical, moisture, and chemical issues.

The RG403/U cable exhibits capacitance of approximately 29.4 pF/ft (96.5 pF/m), signal attenuation of around 29 dB/100 ft at 400 MHz (signal attenuation of the cable depending on the frequency), and has a velocity of propagation of 69.5%.It has a center 7-stranding conductor design measuring 0.012 inches (0.3048 mm) in diameter and an insulation layer measuring 0.034 inches (0.8636 mm) in diameter. This cable is ideal for direct burial applications. It has an operating temperature of -55˚C to + 200˚C.
