Unless you can line up the radiating elements vertically, all your
antennas will be out of phase with other to any other direction.
Some RX signal will go by the first antenna and hit the 2nd 3rd and 4th
antenna out of phase with the 1st antenna. The end result is that the
out of phase signals will lower the total RX signal.
Same thing happens on TX.
Something that may work is transmit with a vertical at the top of the
tower, put each of your beams lower on the tower each to a separate
receivers and a voter. Lots of hardware feedline and filtering
considerations.
Easiest thing to do is a folded dipole array, arrange the dipoles for
major lobes to the areas you want.
Thats my two cents
