Unless over an extensive ground system and avoiding to elevate the antenna
from ground, a vertical array on 10m will not have a consistent energy
radiated at very low angles and no signal enforcement at any elevation
because of ground reflections.
In the other hand, there are moments where a wide coverage of elevation
angles and the capability to vary beam in a short time can be useful in
spite of the cited gaps.
