Re: aluminum boat as antenna
Aluminum hulls should not be wired so that the hull acts as a ground or rather, current introduced as a ground.. Antennae may not have enough voltage on it to start electrolysis BUT, I wouldn't want to be the person to try it out.. Yes auto antenne's are isolated, but an old hotrod trick is to mount them inside the frame rail and they will be hidden and work reasonably well.. As to running the wire direct, after thinking about it. I agree, it won't work like that, still, I don't know as I would add an antennae where it could touch aluminum hull, not because it wouldn't work, but just in the case of introduced voltage. Electrolysis is not a good thing unless your cleaning up a rusty old part.,, AM/FM is not LOS so it does not matter if you tuck the antennae where it cannot be seen altho aluminum makes a pretty good isolator from AM/FM signals as experience from not being able to get good reception in a tin building 7 miles from the station's radio tower
