"Some retired Navy guy" is my term for he whose name I can't
remember. Apparently he is well regarded in the field of marine
HF with 40 years of experience. ME (Marine Electronics) is the
official publication of the NMEA. I was an associate member for a
year so got it every month (or was it quarterly?). I'm pretty sure that
the article was in an issue during the summer of 2002. I tried the
foil-to-thruhull option and it has works great. I had foil strung from
stem to stern tied into keel bolts and everything in my previous boat.
Simpler solution seems to work just as well.

An issue of ME from summer before last pretty much debunked the
idea of building extensive groundplanes into the hulls of boats. Gordon
West and a fella that was a retired Navy guy in charge of inspecting
ships for 100 sq-ft counterpoise compliance did some tests. Four
systems were tried using a modified coax switch to switch the
counterpoise between them. The systems we

1) Extensive mesh glassed into the hull of a brand new Swan.
2) Copper foil hung over the side touching the water.
3) Copper foil trailing 100' brhind the boat.
4) Copper foil wrapped around a through-hull secured with a hose clamp.

Results: No real difference!

I haven't seen any published data like the above, anywhere. Can you
provide a URL or reference for the above? I find that "some retired Navy
guy" to be a bit to much in the "hearsay" catagory, and I haven't paid
any attention to Gordy in years. I have spent 35 years designing,
installing, and Inspecting, LF, MF and HF Radio Systems on Vessels
ranging from 16 ft, to 600 ft, and Coast Stations in the Maritime Mobile
Radio Service throughout the North Pacific Coasts. My opinions are my
own, and are subject to my own experiences over the years. They are
shared freely, when asked for, usually. Others may, and do, hold
different opinions, that may, or may not, be mutually exclusive.

Like I stated previously, "If it were ME"
