Hi,
The closer the better.
Radials can even be submerged by water.
The best being in /MM of course, but then that's not on the beach anymore.
Usually you install your antenna to be safe at high tides because you don't
want water in the connection box / balun.
Salt water will help with radiation efficiency for verticals and near-field
absorption for all antennas but only if your path is over the water.
73,
Yan.
