It's already been/being done. Check out wire for electrified fences at
your local farm store. Mild steel core with copper exterior. I used it
for building VHF transmit/receive antennas.

One more thing: VHF antennas work better when (a) wire diameter is
increased and (b) the wire is polished mirror bright.
