Topband: Inverted L by the sea

Hello, Gents:

I am currently using an inverted L on 160M. The antenna is mounted on the 
end of a pier about
150 feet long. The only ground return I use is a length of 2 inch copper 
flashing attached to a ground
rod driven into the floor of the ocean. It is fed with an UnUn (50 
ohms:12.5 ohms).It works really
well EXCEPT that the resonant frequency rises and falls with the ebb and 
flow of the tide. I am
thinking of disconnecting the ground return and putting out two full size 
elevated radials over the salt

I'm mainly interested is not destroying what is a really good antenna but 
in alleviating
the tidal changes in SWR. Anyone have any ideas about how well (or poorly) 
it might work?
