[Elecraft] K3 on motorboat.

[Barry]

This will look like the 23' HF whip used by boaters and the wire can be 
barely seen. I can't see how this would look much worse than what 
boaters already do for HF except this will be ground independent.

I counsel inverted Vs as they are ground independent. On power boats that too is a tough trick, but it can be done, depending on size of the boat. A 40 meter dipole can be made by bending the ends and can be fed with coax through a 4:1 current balun if the run to the radio is not too great. It will require a fiberglass mast bracketed to the fly bridge. There are several suppliers of good, strong push up masts available; I wouldn't go more than about 25 feet which should put the feed about 31 or so feet over the water,m close to a 1/4 wave on 40. This arrangement will allow all band operation above 40 with a K3 as the tuner is just plain magic.
