What is a Coaxial Cable?

A coaxial cable is a specific type of cable that is made up from copper combined with other metal shield materials and components to block signal interference. They include one physical channel to carry the surrounding signal, usually accompanied with a layer of insulation.

RS Pro RG174 Coaxial Cable

The RG174A/U Coaxial Cables are traditionally used for interconnecting telecoms industry equipment and data. This interconnection is useful for facilitating the transmission of radio frequency signals.

Features and Benefits

• A coaxial communication cable, great for communicating!
• Meets the requirements of MIL-C-17
• Black polyvinyl chloride )PVC) outer sheath
• Stranded 7/0.16mm
• Copper clad steel inner conductor with PE Insulation
• More flexible than RG58
• Impedance of 50 Ohm

Typical Applications

• Wi-Fi pigtails
• Power management
• Communications and networking

How do Coaxial Cables work?

Coaxial cables work through having concentric layers of electrical conductors and insulating material. The way that they are constructed is what ensures that a signal is enclosed within the cable and prevents any electrical noise from interfering with the signal.
