I wouldn't get too excited about this project.
The big groundplane is nice, but doesn't replace
the "vertical on the beach" at all.  The 5/8
wavelength height is good for a few dB at the
most, and even that isn't guaranteed.   Then
as K9YC found out, there is the matter of receiving.W
Especially receiving while the station is broadcasting.
Before even beginning this project, I would advise
installing a temporary receiving loop at the site
and nulling the AM station as best you can.  Needless
to say, you can't use varactors to tune the loop.
See if you can hear W1AW as a start.  That should
be duck soup from 9-land.  Good luck.

YMMV.
