I can only provide anecdotal evidence. In July 1997 we did CY9AA and our 160m antenna turned out to be a 130' wire, suspended by a large helium/mylar balloon.
We mounted the base in the rocks right at the waters edge on the North/Northeast-ish edge of the smaller north Island of St. Paul. Condx were incredible on top band. We worked EU before sunset (unthinkable from home here in VE9) and worked many W6's late in the evening. We got many comments that we were "just about as loud as Jack VE1ZZ".he is also close to salt water, but has a 4-square on a hill. (also a real nice guy) We were very pleased with 160m results. As an afterthought...we had a Battlecreek special several hundred feet from the waters edge on Sable sand the year previous and never really thought we were loud on any band.
