Agreed that they are dispersion-field limited but their inherent broadband
and "directionality" can, if located far enough from the signal sources and
destinations, solve some interesting comms situations. For example,
metropolitan "relays" able to leap tall buildings in a single bound:). They
can complement broader NVIS HF which is less reliable and narrow band.
