The late W2PV wrote an article on crossed dipoles in either QST or CQ in the
late 70's. He put them up high (150' or so) and needed a strong signal in
all directions. At this height the pattern is very figure 8 with nulls off
the ends. Several mobile antennas use this concept at both HF and VHF.
You can used crossed dipoles to also work both ends of 80/75, too. Set one
on 3800 and one at 3525 for example.
