What are RG59 Coaxial Cables?

RG59 Coaxial Cables are a type of coaxial cable commonly used in telecommunications and networking applications. They are designed to transmit radio frequency (RF) signals over long distances with minimal signal loss.

RG-59/A/U

The RG-59/A/U is a 73-ohm coaxial cable with an overall diameter of 0.242 inches and a voltage rating of up to 2300 Vrms. It has an internal copper-clad steel (CCS) or copper weld wire (CW) or bare copper conductor (carrying the electrical signal), which is enclosed by an insulation layer made of Polyethylene (PE). The insulation layer is then completely enclosed by 1 bare copper braid or tinned copper braid, or copper-clad aluminum (CCA) 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-IIA). The jacket protects the cable core from mechanical, moisture, and chemical issues.

The RG-59/A/U cable exhibits capacitance of approximately 21.0 pF/ft (69.01 pF/m), signal attenuation of around 10.5 dB/100 ft at 400 MHz (signal attenuation of the cable depending on the frequency) and has a velocity of propagation of 66%. It has a center conductor measuring 0.0251 inches (0.64 mm) in diameter and an insulation layer measuring 0.146 inches (3.71 mm) in diameter.

This cable is ideal for use in short-distance transmission of signals applications such as radio signals, video communications (cable TV, CCTV), transfers of video signals between DVD players, VCRs, or digital receivers, and synchronization between two digital audio devices.

RG-59B/U

RG-59B/U Cable Structure

The RG-59B/U is a 75-ohm coaxial cable with an overall diameter of 0.242 inches and a voltage rating of up to 2300 Vrms. It has an internal copper-clad steel (CCS) or copper weld wire (CW) (carrying the electrical signal), which is enclosed by an insulation layer made of Polyethylene (PE). 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-IIA). The jacket protects the cable core from mechanical, moisture, and chemical issues.

The RG-59B/U cable exhibits capacitance of approximately 21.0 pF/ft (69.01 pF/m), signal attenuation of around 9.0 dB/100 ft at 400 MHz (signal attenuation of the cable depending on the frequency) and has a velocity of propagation of 66%. It has a center conductor measuring 0.0230 inches (0.584 mm) in diameter and an insulation layer measuring 0.146 inches (3.71 mm) in diameter. This cable is ideal for use in CATV, MATV, CCTV, local area network, digital video, and monitor/VDT display.
