RG58

RG-58/U is a specific type of coaxial cable often used for Thin Ethernet (10BASE2) and low-power signal connections. The cable has a characteristic impedance of either 50 or 52 Ω.When used for Ethernet, it provides a maximum segment length of 185 meters.Most two-way radio communication systems, such as marine SSB, marine VHF, amateur, police, fire, WLAN Antennas etc., are designed to work with 50 Ω cable.
