What are RG22 Coaxial Cables?

RG22 coaxial cables are a type of cable that is commonly used for transmitting high frequency electromagnetic signals, such as those used in the satellite and cable television systems. These cables are designed to transmit signals over long distances and are suitable for use in both indoor and outdoor installations.

RG-22/U

RG22/U Cable Structure

The RG-22/U is a 95-ohm coaxial cable with an overall diameter of 0.405 inches and has a voltage rating of up to 1000 Vrms. It consists of two individually coated bare copper conductors with 7-stranding construction (carrying the electrical signal). The inner conductors are enclosed by an insulation layer typically made of Polyethylene (PE). This insulation conductor is then completely enclosed by two shield layers made of tinned copper braid. The shields form an outer conductor and also provide protection 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-22/U cable exhibits an approximate capacitance of 16 to 18.4 pF/ft and can have signal attenuation of around 10.5 dB/100 ft at 400 MHz (signal attenuation of the cable depends on the frequency). This cable has two inner conductors with each conductor measuring 0.0152 inches (0.386 mm) in diameter, an insulation layer measuring 0.285 inches (7.24 mm) in diameter, and a velocity propagation of 67 %.

RG-22A/B/U

The RG-22A/B/U is a 95-ohm coaxial cable with an overall diameter of 0.405 inches and has a voltage rating of up to 1000 Vrms. It has two individually coated bare copper conductors with 7-stranding construction (carrying the electrical signal). The inner conductors are enclosed by an insulation layer typically made of Polyethylene (PE). The insulation layer is then completely enclosed by two shield layers made of tinned copper braid.  The shields form an outer conductor while offering protection 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-22A/B/U cable exhibits an approximate capacitance of 16 to 16.3 pF/ft and has signal attenuation of around 10.5 dB/100 ft at 400 MHz (signal attenuation of the cable depends on the frequency).
