Two Shunts or One ?

Looks like GenuineDealz has an Anchor brand cable that could fit the situation for about $25.....what do you think of this one?

Marine Shielded Signal Cable Wire 20/8 AWG - 25 ft: 91195025 Genuinedealz

Is this cable suitable? Is 20 Ga. adequate? I would think so since it is only transmiting signals and no significant currents.....

It is not twisted pair as far as I know.That is more important than tinned with this application.

Here you go; tinned and twisted. 50' @ $5.99 @ Fry's (or any computer store)

Forgive me for I am on a learning curve when it comes to twisting. This is done primarily for noice cancelation, correct? Is there any other reason(s) for twisting? Wouldn't shielded cable accomplish the same?

I'll check out the tinned/twisted cable that you mentioned, thanks, SeaHunter....and Mainsail!

This forum is such a benefit to the sailing community

Because you're measuring electromagnetic fields you want to cancel out any extraneous interference by balancing the field(s); twisted pairs do this quite well.
