[TowerTalk] [Bulk] Time for a Real Tower Question TX-489

[Grant Saviers]

I have two 589's and don't see any reason to doubt the PE analysis by 
UST for a 489.  Note that the calcs are for the TIA/EIA 222-F, B 
exposure, 85 mph 3 sec gust.  So a definitive answer is "it depends" on 
the new location, not that these exposure values are in any way 
sandbagging by UST.  A permitting review might require new calcs to the 
G rev standard.
