Commswest Distribution sources their own range of RG58C/U Mil-Spec coaxial cable from high quality manufacturers.
RG58C/U is often used for low-power signal and RF connections with an impedance of 50 Ω. There are several versions with differences in core material (solid or braided wire) and shield (70% to 95% coverage).
Most two-way radio communication systems, such as marine, CB radio, amateur, police, fire, mining, WLAN antennas etc., are designed to work with a 50 Ω cable. It is commonly used on mobile antennas in vehicles to the radio due to its high flexibility and small diameter enabling it to fit through tight areas. This cable can also be used on short runs for other antennas such as base station, but attenuation figures should be checked for desired losses.
RG58 cable can be used from low to moderately high frequencies. Its signal attenuation depends on the frequency as outlined in the table below.
