Re: Cheap cables from China


Not all RG58s are the same. Depending upon whether a cable is RG58, RG58/U, RG58A, RG58B, RG58C, etc. the impedance can vary from 50 ohms to 53.5 ohms without even taking into account differences between various manufacturers and each manufacturer's process control. RG223 might be a better choice, particularly for high frequency applications. It's double shielded and microwave power loss is lower. IIRC, the impedance is more dependably closer to 50 ohms.
