These are the cables that sit between a CB or ham radio, an SWR meter or tuner and the antenna. All of them are 50-ohm coax with UHF connectors: PL-259 plugs on both ends, or a PL-259 paired with an SO-239, FME or NMO fitting for mobile antennas.
Thinner RG58 and RG316 are easy to route inside a vehicle or between stacked radios; RG8X is the common all-round choice; RG213 and KMR400 have the lowest loss for long runs to a base antenna.
