Default RF Ground (Counterpoise)

Any ideas on how to run the copper foil around or through bulkheads. I would like to glass-in copper foil under each one of my watertanks, but I am not sure how to get the copper strap through the bulkhead.

Is it a bad thing to cut the foil and bypass it with something of a smaller surface area. Like a 1/4" copper pipe? Then wrap the foil around copper pipe on each side of the bulkhead.

You could do that, however a single continuous electrical path is preferable. (Low resistance is paramount).

Do not drill holes through ribs, to feed wires through, as I have seen on numerous boats. [:X] I can just visualize a structural failure there in high seas!!

By Ribs do you mean bulkheads or stringers?

Before you start cutting holes in the bulkheads, you may want to read through this controversial subject of ground planes at:

FWIW, I have been using HF radio for over 25 years on my 'plastic' boat on both ham and marine bands using a single 'Dynaplate', 18 inches long. I have no complaints about my signal. Also, I rarely transmit at a power level above 50 or 60 watts for both voice and digital traffic.
