Coaxial Cable

Coaxial cables, also called coax cables, are a form of electrical cable - notably used as TV aerial cable - which carries radio frequency (RF) signals. Historically they have been used to connect satellite antenna facilities to homes and businesses.

Coaxial cables have a distinctive shape which is thick and round due to their interior insulation layer. The most common sizes are: RG-6, RG-11 and RG-59. They also have a transmission speed of 10Mbps (megabits per second) and have a much higher transmission capacity than twisted pair cables. They can be connected to other devices using coaxial cable connectors, such as BNC, TNC, SMB, 7/6 DIN connectors, QMC, MCX, and RCA connectors.

We also provide additional services such as a large range of in-stock items, in-store collection where available, fast & free delivery and eco-friendly options like Better World products.
