I don't know if you'd actually want to try that, but it would probably be a fairly simple mechanism to implement. Personally, I think a motor-driven arrangement would be better so that you wouldn't be at the mercy of the tide. Interesting info too -- thanks for sharing. I would not have guessed at the amount of difference you're seeing between high and low tide. Do you have a pic of this antenna somewhere? IT would help to get an idea of the arrangement for anyone trying to determine the "why" to your changes. -Bill > with this information, I don't know.
