Not currently supported. PCB would also need to treat that copper
differently in its own connectivity scanning code, otherwise it would
merrily extract the whole DC-connected netlist (shorting either side of
the inductor).

Perhaps I was going a bit far to suggest full DRC for the actual antenna
design. What I really meant was not loosing information for net
connectivity checking leading up the antenna.
