Some years ago, on 80 meters, an LZ station had a horizontal between two tall buildings and had a very strong signal.

Large buildings are not towers or poles. Buildings have a significant amount
of large conductive metallic things and noise generating junk inside.
A vertical also will have a null below the antenna, nulling building
coupling for RF. A horizontal has maximum possible signal into and out of
the building. Even with a 400 ft high building, a horizontal antenna a
fraction of wave over the roof can be very disappointing.
