WOW! 12 towers. I've only worked with a 3 tower directional array
that was switched between 2 frequencies and 4 different patterns. A
small 100 KW shortwave transmitter and it too switched between the 2
frequencies. Flip the switch and hope that the TX quenched as it
should, all switched as they should and came back up at 100 KW. A bit
u-nerving when all of this happened. I do recall once there was a
flash over in a tower switching unit which set the sagebrush on fire.
Made for an exciting afternoon.

The Phasor used by directional stations is not a matching unit. It is a power
divider phasing unit as each tower gets different current, phase to develop the
pattern. Each individual tower has an ATU. The phasor for a 12 tower station
is fascinating as is the pattern.
