It's a phased array. No wires, the tower is the antenna. It sits on
isolated plates.
They point in certain directions so as to be available for the
handy-dandy AM emergency-whatever-coverage.


Clarification for the original poster: that is an AM radio antenna
system. As Woody said, the towers are the antennas, no wires. The towers
are all connected by coax and fed in phase so as to provide a directional
Transmit pattern. THey probably did it this way because the FCC mandated a
specific coverage area for their license requirements.
