At the feed point, one can mount something like an LDG
auto-tuner.  Those devices can handle a pretty high
SWR and will probably allow you to run the above antenna
on all the bands 80 and up.

In a 40x20 attic, you can probably fit about 110' of wire
by going around the edges as shown in Mirko's diagram.
