UNITY—Michael Willette’s financial future could rest in the hands of the town’s planning board.

Willette, who owns Stargate Cell Tower in Winslow, built cell tower on Route 202 a couple of years ago on speculation, counting on a town ordinance he believed would force cell-service providers to rent space from him when they moved into the area.

Now, Willette is afraid of losing his monopoly on coverage in the area if the planning board approves U.S. Cellular’s plan to build its own tower just a few miles away.

The planning board is scheduled to hold a workshop on the application at 7 p.m. Tuesday at the community center. The board is expected to schedule a public hearing on the application during Tuesday’s meeting.

U.S. Cellular first submitted an application last year for its own 190-foot cell tower on property owned by Michael and Donna Mesaric, off Leelynn Drive. The site, just a short distance off Route 220, would give the company coverage in much of Unity and into Thorndike, based on documents filed with the town.

The U.S. Cellular also would have space to rent to five additional carriers.

Unity’s telecommunication ordinance requires companies to make an effort to use existing towers, but there is room for interpretation, said planning board Chairman John Piotti.
