Really not good…. The antenna should be isolated from the back stay
base and head and the “hot” part of the antenna should start out of
reach of human hands and heads. Any connecting wire from the tuner to
the antenna should be well insulated.

I haven’t really validated all this for myself, but here is how the previous owner described the antenna setup on Deep Playa, #152.
“The Antenna Tuner is mounted forward in the Port cockpit locker. The antenna tuner has two connections. The antenna side is connected with #8 stranded wire to the chainplate for the main backstay. All the chainplates were bonded together (along with through hull fittings, etc.) with #8 stranded wire. The ground wire that was attached to that chainplate was removed and attached to the grounding terminal on the antenna tuner. What you end up with is a whole series of closed loops instead of a single separate isolated antenna wire and a large ground plane in the bilge. I cannot explain how it works, but it does.”
I think I’ve come to understand this as the antenna consists of a random length wire hooked to a really nice antenna tuner. The random length wire is made up of all of the standing rigging bonded together.
