One idea - there was an article in QST some years ago about using a
trap to make an inverted L. Fellow had an 80m vertical. He added a
trap for 80m and then ran a wire out horizontally.
You could probably do the same thing for 40m/80m. One pretty
foolproof way to make a trap is to wind coax on a PVC form. There's
even a freeware program out there to compute the length of the coax -
Coaxtrap. Google for it.
If you're going to make 80m a habit, some 50-60 foot radials would be
nice. K2VCO should also consider some longer radials.
