Actually, the 88 foot doublet is designed to cover 80-20m and  
maintain a bidirectional pattern. And thats when it is suspended from  
100 foot supports. It's no great shakes on 80m, because it is a  
little short, but this preserves the bidirectional pattern on 20m.

If you are just looking for a fixed-compromise antenna that covers  
80-10m, then the 140-102 foot doublet fed with open wire does quite  
well. Length isn't critical.
