Uhmmm...this isn't one of those ionosphere posts is it? Butch Will wrote: I want to set up a hf antenna for my sailboat. I have read various guides from Icom etc. They suggest running copper foil to a Dynaplate and use sea water as the ground. How can this work when the Dynaplate is below sea water? Is sea water equal to copper wire radials as a RF ground system? Does sea water make a good enough ground without radials? How can a piece of copper metal about 1 ft square equal several radials laying on the boats deck? Why do i have to use copper foil when most other people suggest using ordinary copper wire? Over seawater what would be the best number of radials to use considering that maximum length i can run is 40 ft. I am planning to use a backstay antenna with a SGC 230 Tuner. All ideas and comments appreciated. Will No, Not an Ionsphere Post, just a guy who has no clue about the technology that he wants to use, and he is asking questions, trying to learn. From the replys he has received so far, he is finding out that 99% of the hams, don't have a clue about MF/HF Marine Radio Antenna systems Design, either. I suggest that he head on over to rec.boat.electronics, and ask Larry, Gary S., Old Chief Lynn, or one of the other Old Salts, that have been doing these installations for decades, and have the experience in the technology being asked about. Most hams think that MF/HF Marine Radio Antenna Systems design should follow the same rules that Land Startions use. Well that isn't the case, and usually ends up is a "**** Poor", marginal system that only talks "when the Band is open", and "when the Band is open" even a wet noodle will radiate enough to communicate.
