I don't know - BUT - wouldn't you install a motor to turn the antenna so it
could be adjusted to several signal sources?

Here is a standard roof antenna:

Which end of the antenna is supposed to be pointed in the direction of the
signal source? The left end (the end with the the longests elements) or
the
right end (the end with the shortest elements)?
