EZNEC permits you to specify any conductivity and permeability (copper
and 6061 aluminum alloy are pre-defined for convenience). However, the
same combination applies to all wires. In practice, this is usually
acceptable when wires are of different materials because generally one
part of the antenna dominates the loss.
