I'm curious why they still do this.  The physics is well within our
ability to do computational modeling, so there should no longer be any
need to build an actual physical model.  If the AM people can "proof"
their directional arrays using a computational model (method of
moments) and some simple measurements, it should be possible to model
VHF antennas the same way.
