Yes, the antennas are made from aluminium but this doesn't mean that the antennas insulate something. The emissions of an antenna are obtained through an alternate current.
This is different from the property of being a good medium for the propagations of an EM field.

What's about electro-magnetic shielding?
Aluminium is not known to be a perfect insulator for high frequency emissions of RF...
