SSB Ground Question

What's the best way to connect the copper ground strap to the bronze through hull? My through hull doesn't have any kind of lug or bolt on it. Can I clamp it on with a jubilee clip (hose clamp)? Or is the stainless jubilee clip versus bronze and copper a galvanic no-no? Is there such a thing as a copper jubilee clip (couldn't find through Google)?

P.S. Does anyone know whether the Icom AT-140 tuner is DC current isolated? Or do I need to install caps into the ground strap? I would hate to be sunk by a galvanically destroyed through-hull.

Re: SSB Ground Question

Dockhaed,
I'm short on time...

1- Yes the AT-140 grd is DC isolated..

2 - Use Penetrox-A conductive grease on the bronze - copper - stainless connection....it is designed for dissimilar-metal conductive connections...
(been using it for 30 some years...works great and is cheap!! but messy!!)

3 - If you're looking for an alternative way, there ARE SS Clamps with "studs" on them to easily allow connection of wire, wire lugs, or copper strap (with a hole punched thru the strap)...
DX Engineering sells them!! (as well as sells the Penetrox-A)

4 - Dave, on "Auspicious", has posted in the past about his procedure for attaching the copper strap to the thru-hull....so a search and you'll find his posting....


Sorry don't have time to find the relevant pages / links right now...

Re: SSB Ground Question

carefully drill and tap a #10 hole in the seacock flange. Use a blind tap. Put a screw in. Dont do this unless you are capable! Are you sure there's not a small hole already on the flange?

There's no flange as far ad I know, but I'll have a look!
