Thanks for your interesting post. I want to use my FT897D with a FC40 on board my sailboat and I read many proposals for the "good length" of the isolated backstay, I had thought to 12.5m but as you say it does not work I shall keep your suggested 9.6m length BUT what do you call a 0.4m pigtail ? Could you explain lease, I would like to have the system working well on all HF bands.
73s and best regards from FK8IH

The wire antenna is 9.60m long, and tunes all freq but only upper
part of 80m. To make it tune 80m I have to add a 0.4m pigtail to the
antenna connection of the tuner, parallel to the antenna wire.
