If all of the elements are parallel as in your photo, then it's
bi-directional. If you drew a line through one element, through the mast,
and through the other element, maximum radiation would be along that axis.
If the elements are staggered such that each bay pair is rotated 90 degrees
from the bay above/below it, then it's basically omnidirectional.
