The overall tower height is 227 meters. According to §73.160, the "A" dimension for sectionalized towers is the height of the lower section of the tower, in electrical degrees. The FCC table shows an A dimension of 120 degrees, which for 1040 kHz converts to 96 meters. So the top section would be 227-96 = 131 meters, which would convert to about 164° at 1040 kHz (assuming I did this right).
