The 80 m dipole feed with ladder line and a tuner can work well even with multi lobes on the higher bands.
See any edition of the ARRL Antenna book or handbook for typical patterns, or www.cebik.com antenna web site for patterns. If you take into account the lobe directions you will have fine results. Just orient so that lobes are mainly in directions of ham populations on the higher bands. Stuart K5KVH
