Looks like our local Home Depot has that Noalox, thanks for the tips on that. Since I am now looking at mounting the antenna on the pole that the white light is on I will need to run a wire down to the boat body from the L bracket right to create the ground plane since the pole it's on doesn't seem to be a very good electrical conducter as far as I can tell so far. So I would use that noalox at the point the wire connects to the boat and would I still get the same ground plane effect from the antenna being roughly almost 3 ft above the boat?
