What this outcome means
The FAA studied the proposal and concluded it would not be a hazard to air navigation. A no-hazard determination is not permanent — it carries an expiration date, and if the structure is not built by then the case has to be re-filed.
The proposal, in the filer's words
"T-Mobile proposes to replace antennas on top of an existing approximate 110' building. The building was built in approximately 1982. The overall height with the antennas will be approximately 115'. It's noted that another carrier's antennas have the max height of 115'. TMO's proposed replacement antennas will have a rad center of approximately 107'-108'."
