<P> Most two - way radio communication systems, such as marine, CB radio, amateur, police, fire, WLAN antennas etc., are designed to work with a 50 Ω cable . </P> <P> RG - 58 cable is often used as a generic carrier of signals in laboratories, combined with BNC connectors that are common on test and measurement equipment such as oscilloscopes . </P> <P> RG - 58 in versions RG - 58A / U or RG - 58C / U was once widely used in "thin" Ethernet (10BASE2), for which it provides a maximum segment length of 185 meters . However, it has been almost completely replaced by twisted - pair cabling such as Cat 5, Cat 6, and similar cables in data networking applications . </P> <P> RG - 58 cable can be used for moderately high frequencies . Its signal attenuation depends on the frequency, e.g. from 10.8 dB per 100 m (3.3 dB per 100 feet) at 50 MHz to 70.5 dB per 100 m (21.5 dB per 100 feet) at 1 GHz . </P>
