Water towers in the Chicago metropolitan area are used by commercial land mobile; public safety (city, country, state) and commercial mobile/cellular companies (e.g. AT&T Wireless; Verizon Wireless; T-Mobile; Sprint). The last group historically has paid significant $$ for specific locations or cell sites -- that has been changing recently. One real estate management company wanted to double the lease fees -- the mobile (cellular) company promptly removed the antennas, feedline and equipment from all of their properties.
While you may be dealing with anti-technology/anti-science thinking (prevalent in some areas) ---- it is much more likely they are more capitalistic --- wanting $$$ (monthly or yearly lease payment). Money talks in this current recession and they will actively pursue cash flows like a lonely man in the desert looks for water. w9gb
