What are RG180 Coaxial Cables?

RG180 Coaxial Cables are a type of cable that forms an essential component in many electronic and networking systems applications. They provide an excellent signal integrity and low signal loss, making them suitable for long-haul communication links. A high degree of durability and flexible design makes them ideal for both indoor and outdoor scenarios.

RG180/U Cable Construction

The RG180/U is a 93-ohm coaxial cable with an overall diameter of 0.140 inches and a voltage rating of up to 1500 Vrms. It has an inner silver-covered copper-clad steel (SCCS) wire (carrying the electrical signal) with 7x38 stranding construction. The inner conductor is enclosed by an insulation layer made of Polytetrafluoroethylene (PTFE). The insulation layer is then completely enclosed by 1 silver-covered copper (SC) 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 Fluorinated ethylene propylene (FEP-IX) or KEL-F (PolyChloroTriFluoroEthylene). The jacket protects the cable core from mechanical, moisture, and chemical issues.

The RG180/U cable exhibits capacitance of approximately 15 pF/ft (49.34 pF/m), signal attenuation of around 17.0 dB/100 ft at 400 MHz (signal attenuation of the cable depending on the frequency), and a velocity of propagation of 69.5 %. It has a center conductor measuring 0.0120 inches (0.3048 mm) in diameter and an insulation layer measuring 0.103 inches (2.6 mm) in diameter.
