when I purchased my boat there was copper strap running under the aft cabin
and run to the engine
, it was loose and badly corroded. I would rather not reinstall the copper strap.
thanks for any comments.
1. The ground refers to a DC ground path, not an RF "ground" which is not a "ground" at all but a counterpoise which mirrors the earth side of an antenna
. Two very different things which, although some think should be connected and also connected to a thruhull, should be mutually exclusive things to avoid interaction and stray conducted noise
on the receiver. There are also safety
consideration which argue for separation - a ground short could put power places you never intended or want making the combined DC/RF thruhull connection not worth the dubious benefit to my way of thinking.
2. Copper is a far better conductor but it's all in what you feel is adequate - the toe rail located channel, if you could figure out a way to make an electrical
connection without dissimilar metals, will work but not as well.
