I wonder if they had to wire up those fluorescent fixtures or they're lit by the ambient RF alone?
When I was a kid we went to the Outer Banks every summer. Mom had relatives near Greenville, her first cousin taught at ECU, then ECC, so it was a stop on the way down or the way back. We would go past those things and I would wonder "What the heck are all those antennas doin' way out there?" They were really cool at night when they were all lit up, you could see them for miles in that flat terrain and swamp.
