Folded monopole w/ Al sailboat mast?
 

It would seem that a 40+ foot aluminum mast with a grounded bottom
just calls out for a wire from its top, parallel to it, down to a
deck-level feedpoint with a tuner.

Does anyone have any experience trying to do this? Was it any better
than the typical weakening of your backstay with insulators? (I have a
B&R rig, so I don't even have a backstay, anyway.)


Good listening,

That configuration is no better than shunt feeding the mast near the bottom,
and is a lot more complicated mechanically, particularly keeping the wire
straight and parallel to the mast. Put a stainless hose clamp around it
about a foot from the bottom, feed it through a tuner there and see what it
does. Replace the tuner with a fixed network(s) when satisfied.
