As hams, we buy a tower based on what we think it'll support. Commercial
buyers do just the opposite - they tell the factory what they're going to put
on it and the factory tells them what they'll need. These are 'engineered
towers'. Towers like 25G, 45G and Trylon towers are NON-engineered towers.
Engineered towers are ones that calcs have been run on and as the
customer, you're going to get a 'custom' tower; i.e. Rohn has several
different configurations for each SSV section depending on load and windspeed.
