No. There are certain physical effects that come into play at high frequencies which are not significant at low frequencies or DC - to simplify greatly, the space around the cable is itself electronically active, not merely the metal part itself. That's why you need coaxial cable, not just two wires side-by-side like regular mains power cable. This also means that you can't reliably splice coaxial cable without very careful consideration of the joint geometry.
