What are RG62 Coaxial Cables?

RG-62 Coaxial Cables are a type of cable that has been designed for carrying high frequency electromagnetic signals over long distances, owing to its high degree of signal integrity and lower signal loss.

RG-62/A/B/U

The RG-62/A/B/U is a 93-ohm coaxial cable with an overall diameter of 0.242 inches and a voltage rating of up to 750 Vrms. It has an inner copper weld wire (CW) or copper-clad steel (CCS) wire (carrying the electrical signal) with 7 x 32 stranding construction. The inner conductor 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 RG-62/A/B/U cable exhibits capacitance of approximately 14.0 pF/ft (46.05 pF/m), signal attenuation of around 8 dB/100 ft at 400 MHz (signal attenuation of the cable depending on the frequency) and has a velocity of propagation of 84%. It has a center conductor measuring 0.0240 inches (0.612 mm) in diameter and an insulation layer measuring 0.146 inches (3.71 mm) in diameter.
