Well, a silver plated antenna probably WOULD conduct better than pure
aluminum! But would you pay for it?
Perhaps the Q of an antenna is not critical like the Q in a resonant
cavity. Material losses cause a decrease in Q which kills the resonance
of the cavity. I suppose it affects the antenna as well, but probably is
something we can all live with.
