I've been trying to unravel the mysteries of SSB grounding in yachts
and found some information about using resonant ground wires in an old
discussion group archive. I would like to try this antenna grounding
setup, rather than try to coat the inside of my boat with copper foil
etc, but have a couple of questions.

At the moment I have a 23ft whip antenna on my boat linked to an ICOM
140 tuner and then copper strap to a copper plate on the outside of
the hull, but I don't think the performance is very good.

From my reading it looks like I need to run two ground wires for each
of the frequencies from the tuner:
Freq Length ft
2mhz 62 (instead of 117ft)
4 59
6 39
8 29
12 20
16 15
18 13
22 11
25 9

My boat is a catamaran. I have wiring conduits that run about 23ft on
either hull and then across the hulls, front and back about 14ft long.
Would it be ok to run these wires in the conduits or do they need to
be "spaced out" in the boat. If I can use the conduits I thought about
running one set clockwise round the boat and the other anti clockwise
- there will be some overlap on the longer ones - would this pose any
problems ?

Thanks
