For concerns on the effect of the antenna wire on the strength of the rope
, my first thought is that this effect will be there but it must be much less than the splices on the stays themselves, because for those splices, the whole rope diameter enters through the braid into the hollow core so the thinner wire has less effect. The rope splice should be tapered, often ending with just one strand, so I would keep my wire at or under the diameter of a single
strand of the rope.
: yes, this would be the reason that I would choose for another way. We have no back stays at all and I use both a long whip antenna and a wire that I hoist. I don't really notice any difference between the two systems. We can't have a wire hoisted while sailing (same reason as we can't have back stays... the sails
can't pass when tacking/gybing) but if I could, I might prefer that over a whip antenna. Have a good look at how some Amel's do this (I like that setup).
