The link below shows the transmit site used by WFAN (which is diplexed with
WCBS into the same vertical monopole). The site is located on a small
island in Long Island Sound.
The horizontal distance along the surface of this island on the ENE radials
reaching the sea water of Long Island Sound is about 300 feet from the base
of the monopole. So toward that azimuth sector, this transmit site is about
as close as practical for claiming a "vertical on a beach."
The groundwave fields from this site are strongly affected by the nearly
100% sea water path lengths to the ENE, down Long Island Sound. However the
radius to the FCC 0.25 mV/m skywave values shown in the link of the OP show
no enhancement in that sector over those fields radiated in any other
azimuth.
