Better yet, just open "Electronics and Radio Engineering by F.E. Terman,
the 1955 edition to page 867. Examine Fig. 23-3 and Fig. 23-4.
Notice that fullwave antenna has 4 lobes almost equally spaced around
its center. That places them at quite an angle as compared with the
lobes of a halfwave antenna. The fullwave pattern results from phase
reversal at the halfwave point,

The fullwave antenna`s pattern is usually something to be put up with
when operating a halfwave antenna at its second harmonic. The resulting
pattern is usually considered undesirable. I wouldn`t tilt a tower by 44
or 45 degrees to make one of its lobes parallel with the earth.
