Please check the pattern on 60 and 40m where the 37m high vertical is going
to be used.
You certainly will see the high angle lobes.

The free-space pattern of current in a vertical (and also horizontal)
antenna is crescent shaped with its maximum at the midpoint, and a minimum
at each end. It shows nothing that could be termed an extraneous lobe. Any
such lobes would seem to be the result of improper matching, or more likely,
the fact that in the real world such an antenna is in an environment that is
certainly not free space.
