North Dakota tower

[Dave Doherty]

I just had a look at the current FAA Advisory Circular AC 70/7460-1K 
regarding tower lighting standards. They provide standards for structures of 
all types, including towers up to 2200'.

http://www.fcc.gov/mb/policy/dtv/lighting.html sets out the presumption that 
structures over 2000' are jointly assumed by the FCC and the FAA to 
represent an inefficient use of airspace. I recall seeing 2049' as the 
maximum some time ago, and that would be consistent with the combination of 
a 2000' limit and rounding to the nearest 100'.
