The shielding of baseband coaxial cables is usually a copper mesh structure with a characteristic impedance of 5092. The cable is used for transmitting digital signals. The commonly used models are rg-8 (thick cable) and rg-58 (thin cable). The most obvious difference between a thick cable and a thin cable is the diameter of the cable. Thick cable is suitable for large local network, its standard distance is long, high reliability; But the thick cable network must install transceiver and transceiver cable, installation is also difficult.
