What are RG392 Coaxial Cables?

RG392 Coaxial Cables are a type of cable that has been designed to carry high frequency RF signals over long distances. These cables are therefore suitable for telecommunications and wireless applications.

RG392/U

The RG392/U is a 72-ohm coaxial cable with an overall diameter of 0.475 inches and a voltage rating of up to 5000 Vrms. It has an internal tinned copper conductor with a 7-stranding construction (carrying the electrical signal), which is enclosed by an insulation layer made of Chlorinated polyethylene (CPE) & Polyethylene (PE). The insulation layer is then completely enclosed by 1 tinned copper braid shield that forms the outer conductor and also provides shielding against electromagnetic interference (EMI). The shield layer is then covered by a layer- called a jacket - made of Polyvinyl Chloride (PVC). The jacket protects the cable core from mechanical, moisture, and chemical issues. Finally, the structure is covered with an outermost layer-called armor. The armor is made of an aluminum braid and offers extra mechanical protection to the cable.

The RG392/U cable exhibits capacitance of approximately 23.0 pF/ft (75.5 pF/m), signal attenuation of around 15.0 dB/100 ft at 400 MHz (signal attenuation of the cable depending on the frequency), and has a velocity of propagation of 64%.It has a center 7-stranding conductor design measuring 0.0477 inches (1.21 mm) in diameter and an insulation layer measuring 0.048 inches (1.219 mm) in diameter. It has an operating temperature of -55˚C to + 80˚C.
