Tunable on many bands except 160. I suppose I could short the leads
together to get 160m but I don't do that.

There's another way to put your 80m loop on 160m for
NVIS operation. Cut the 80m loop directly across from
the feedpoint and install a good insulator. Use that
configuration for 160m and short out the insulator for
all higher bands. I'll let you come up with a cute
shorting arrangement because whatever switch you use
has to withstand thousands of volts on 160m.
