What are RG17 Coaxial Cables?

RG17 coaxial cables are an essential component in many electronic systems and networking installation applications. They offer excellent signal integrity and low loss during signal transmission, 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.

RG-17A/U

RG17A/U Cable StructureThe RG-17A/U is a 52-ohm coaxial cable with an overall diameter of 0.870 inches and has a voltage rating of up to 11000 Vrms. It has an inner bare copper conductor (carrying the electrical signal), which is enclosed by an insulation layer typically made of Polyethylene (PE). The insulation layer is then completely enclosed by a bare copper braid shield that forms an 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 RG-17A/U cable exhibits an approximate capacitance of 29.5 to 30 pF/ft and has a signal attenuation of around 1.9 to 2.8 dB/100 ft at 400 MHz (signal attenuation of the cable depends on the frequency). It has a nominal inductance of 79.8 nH/ft. This cable has an inner conductor measuring 0.188 inches (4.775 mm) in diameter, an insulation layer measuring 0.68 inches (17.3 mm) in diameter, and a velocity propagation of 66 % to 67 %.
