Zorch is correct -- 377 Ohms for free space.
For metals -- they act as shields, so the effective impedance would be very low (acting as shorts to ground).

Electromagnetic waves do not travel in metal. They travel in the vacuum/dielectric around the metal. What the impedance of that metal/vacuum/dielectric configuration is depends on the geometry, boundary conditions and the dielectric.

In free space, 377 ohms in the far field.

in free space? and in metals?
since when has a metal been classed as free space?
DUH!
