At RF frequencies the coils are shorted electrically because
there is a lot of capacitance between them. It won't work much
better than a piece of metal the same size. Coils can be useful
as part of an antenna if the turns are farther apart but as an
element to pick up RF energy from the air medium it will work
poorly.
