Hi Tom,
this sounds very interesting. I certainly look forward to the
construction article & the pictures.
I have an 80m - 10m Radioworks carolina Windom as my main
multiband antenna . It is the cw160s but not very good tx on 160m.
Fortunately I have my Helical for that.

Thanks for writing Tom.
Regards,
