SSB counterpose ground system
- To folks that have installed SSB, how have you handled the ground for the
unit? I understand that the best way is to have about 100 sq. ft. of copper
foil glassed into the inside of the hull below the waterline. Has anyone
done this? Can you solder the foil together? Do you need something like
copper flashing? If you use a dynaplate, how long does it last? Please, what
has your experience been? Thank you.
I spent MONTHS thinking that issue through and researching. This is what I
decided to do and I'm sure others disagree. I have only used the SSB a few
times but I have not heard that anyone can't receive my signal. I also got
into Sail Mail across the continent.
Contrary to usual practice, I did not directly tie the engine block into the
counterpoise network. I am very concerned about galvanic action (no zincs
in engine). I have also yet to connect the transceiver case into the
counterpoise but may do that this year.
I bought 25 feet of 3 inch foil. I scrubbed and scuffed a path for it from
the stern (tuner), past the tank, the engine, under the battery box (removed
for access), under the bulkhead, under the nav station, along the side of
the water tank and ending at the mast step. I had a small dynaplate beneath
the head and ran another piece of foil from that back to the same place at
the mast step. I drilled a 5/16" hole down the mast step into the lead keel
and tapped it and threaded in a bronze bolt which I had converted into
threaded rod by cutting off the head. I seal. the rod in place with 5200.
After folding the foil into an arrow head and soldering the folds, I drilled
it and attached it to the rod by capturing it between two nuts.
Attached is a drawing.
