Now, why would you say that ?
It's known that the efficiency of a skirted stick is always slightly LESS than
an equivalent series fed !
In other words, the feed system has virtually NOTHING to do with the
efficiency of radiation, and a skirt is nothing more than a feed system !
By "unipole" I'm assuming you mean a skirted grounded stick
of the same construction type used to support freeway lights
as opposed to a conventional lattice tower ?
Note that their is no difference as far as radiation, though a conventional
tower has less wind loading.
