Ground Plane for aluminum boat
 

Does anyone know how to attach a 3-4" copper foil (ground plane) to an
aluminum boat from the antenna turner??

Thanx

Drill big holes in the bottom of the boat and use big stainless bolts
and tighten the bejesus out of all of it!!!!!!!!!

NOT Aluminum is metal. It is a good conductor. Why add copper?

I've been told NOT to attach copper to and aluminum hull.. It will eat
the aluminum..

Can I use an aluminum 3-4" foil??

Hmmmm, You say you have an Alumiunum Hull, that you would like to use
as an RF Ground for your MF/HF AutoAntenna Tuner, at least I assume it
is an Autotuner. Why are you using Copper foil in the First Place?
Just how far is the AutoTuner mounted from the Aluminum that you would
be using for RF Ground? I suspect that maybe your Autotuner is mounted
ON the aluminum, that is part of the Hull, or at least welded to the
the Hull, in which case a two inch hunk of #12 Copper, or if you prefer
Aluminum, Wire, from the Ground Stud, on the Autotuner, to one of the
Mounting bolts of the Autotuner, will be MORE than enough to do the job.
Now make sure that you Antenna Lead coming of the Antenna Port of your
Autotuner, is NOT tyewrapped to ANY portion of the Aluminum Hull, or
any portion of anything that is Welded or Grounded to the aluminum
Hull. Keep you antenna at least 6 Inches away from ANY Grounded
Surface, for its entire run, to the far end of the Antenna System

There....that should work just "Jim Dandy", or Spiffy as the case may be

I'm afraid of using copper. Can the 3-4" aluminum be use instead of
copper foil??

RF isn't too finicky about "foil"....or roof flashing....or even wire, as
long as it doesn't have any of those yachtie-neat sharp turns in it. As
a matter of fact, the more SHORT paths to that nice aluminum hull, the
better!

Polish off the aluminum oxide that coats everything, including the end of
the aluminum wire from the tuner ground post. Use several RING, not
spade (yecch), terminals crimped to several aluminum wires on the ground
bolt. Run these wires in different directions to the NEAREST bolt you
can find. Polish the bolt and all surfaces of oxide. 3 or 4 parallel
grounds in different directions makes a VERY low impedance RF ground
that'll work great. (I'm envious of anyone with a METAL boat, not
plastic with no ground.) We're looking for the shortest ground wire to
the metal boat with the least turns and NO SHARP TURNS, no matter how
"neat" it looks.

Make sure you run through all the channels and RETUNE the tuner on each
frequency after making any changes to antenna or ground installation as
the whole tuning chart needs to be redone by the computer.

You should see the ham club's metal boat....the USS Yorktown (CV-10)
Naval Museum at Patriot's Point in Charleston. Their ground is a WHOLE
AIRCRAFT CARRIER! Signal reports read like we were a 50KW broadcast
flamethrower...(c; Club callsign is WA4USN (United States Navy), of
course...

Hey Larry,

Here is a bit of trivia for you.
Who welded the name on the CV 10 while she was at the Bremerton
shipyard geting refit for jets and Korea?

Naa, it was my mom.

She also built Liberty ships in WW2 at the JA Jones yard in GA. Her
name is Rebecca. Just a litle triva for the guys back on the Yorktown.

Next time I'm in the Yorktown office, I'll tell them. They love those

Tell Mom she's STILL a great ship....

That seems to me to call for a 12" dia hole in the pilothouse top and
a corresponding maybe 14" dia feed-through. Is that the case? Most
commercially available seem to be about 3-4" dia max.

Only if you mount the Sealed Autotuner inside the Wheelhouse, rather
than outside on the Top, or Rear Wall under the DripLip. If 4" is the
biggest FeedTru you have ever seen, then you don't get out much, and see
commercial Marine MF/HF Installations aboard SOLAS Required Vessels.
The "Real Question" in most of these non-commercial Installations has
always been, "Do you want it to WORK, or do you want it to LOOK Good?".
Most say "Work", but a few say "LOOK Good", then at that point, you get
what you pay for.......
