Thanx Hanz 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? G |

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

Thanx Hanz 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 Bruce in alaska -- add a 2 before @ |

I'm afraid of using copper. Can the 3-4" aluminum be use instead of
copper foil?? Hanz Larry wrote: Hanz Schmidt wrote: 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?? Hanz Yes, but why? You don't NEED to. |

: 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... Larry W4CSC....for Charleston South Carolina -- While in Mexico, I didn't have to press 1 for Spanish. It just isn't fair. |
