This shot gives a good comparison of the old and new ATU buildings. The new ATU buildings are much larger, because they must house the combining network for each of the three stations which will use this site. (Once the transmitter building is filled with transmitters and phasors for the three stations, there won't be enough room for five combiners, and since all three stations have different patterns it makes just as much sense to put the combiner for each tower out in the ATU.)
