  A radio tower insulated against ground used as tower radiator for medium wave

A radio tower can be an antenna of a transmitter operating on low frequencies. Such a structure is called mast radiator or tower radiator. As it is possible that a mast or a tower can as well work as radiator and as antenna carrier, a separate attribute may be sensitive as the attribute type is also used for other purposes.

See man_made=mast and man_made=tower for mapping and tagging.
