This is my first post to the Coldwarcomms list. Anyway, I have a lot
of knowledge re: activities on former WU sites. Unfortunately, since
I am current American Tower management employee, I can't volunteer
any info on current ops and tenants, but I can confirm data about the
past, along with some current data that is in the public domain. The
FAA is on some former WU sites, and has towers on land that was
purchased from WU that was adjacent to existing MW sites.
Re: Former ATT sites. American Tower Corp. (ATC) is in the process
of purchasing approx. 1900 former ATT MW sites, about 50 % of the
total. From ME-VA, I would say that we have about 80% of the former
sites, including a number that also supported L-carrier repeater and
master group switching (no former Autovon switch sites, though) with
some underground facilities. There are plans to remove horns on some
sites to accommodate new wireless tenants, but not much has been done
to date. Check out www.americantower.com for more data in the near
future on these sites.
I'll try to answer any future questions as best I can.
