These RG58 cables have an SMA/Male connector on one side and an SMA/Female connector on the other. RG58 cable is thin and flexible, making it very easy to install, but has more loss than other options (average loss of about 2db at 10').
These cables are typically used as an extension cable for antennas terminated in SMA/Male, or to connect an antenna with an SMA/Male connector to an amplifier or router with an SMA/Female connector.
