The tuner (coupler) should not need a counterpoise just a good

That is true about the ground. A counterpoise, however, will help in
antenna efficiency (an antenna in seawater is a whole different
story). This is also mentioned in SGC's own website
".
And, while the coupler (and all similar auto couplers) SHOULD be
"length insensitive", they are not. That's why it JR should try adding
or subtracting the length. BTW, the FC-40 and others will tune loops.
I'm using a 205' hybrid delta loop right now with my AH-4 coupler
(with no ground rod).
