Never mix RG-58 U and RG-58 AU. As the frequency of a signal increases, electrons have a tendency to 'surf' the edge of the copper. Since RG-58 AU has more surface area than RG-58 U, a 'traffic jam' occurs at the junction point, which causes a reflection of some of the signal, creating noise out of your Ethernet signal.

Regardless of the use of RG-58 U or RG-58 AU, the maximum length is 185 meters (or about 200 yards).

The connectors are much more benign, and are called BNC. Because of the debate over what exactly BNC means, it is not identified here.

When using Thinnet, each BNC is attached to a 'T' type device with the cable crossing the top of the T. The base is used to connect to the NIC in the PC. This creates one long continuous segment, known as a backbone.
