Photos would be nice, or at least tell us what kind of antenna this is for a start.

Salt water or just water? Mud?

Your coax may need replacement, too.

If there are any "sealed" boxes for cable/matching network it is worth opening that to let the water out.
You'll see also if there is any corrosion there or other problems.

Often it is better to have a small hole at the bottom side of a sealed box than to have it sealed.
Any crack can turn the sealed box into a perfect water container, water gets in and stays there for
very long time.

A small hole would permit the water to ooze out.
