We examined applications for environmental notice to the FCC for the last month.  Here are the companies that have been most active in submitting to the FCC over that time frame.  Notably, Tillman is still active, outpacing other tower companies.  Vertical Bridge is next up with 36 new submissions, primarily under a subsidiary named “The Towers, LLC.”  Verizon (including Alltel) and AT&T also crack the top 5.  Boldyn Networks was previously Mobilitie.  There are also a number of mid-sized tower companies on the list.  Many of these new towers are being built as build-to-suit towers for AT&T and Verizon, along with a lesser number of towers for T-Mobile.

Compare this to our list of the top tower companies in the United States organized by number of towers.
