The article explains the proper use of tower shadowing in radio engineering. It states that engineers use the tower shadow to protect against interference to and from other systems and the antenna must be placed at the top of a tower with no other antennas nearby. The tower can be used to shadow the signal in the direction of the co-channel system and to shield one system from another on the same tower by placing the antennas on opposite sides of a structure.
