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
"The previous filing underwent an extension that expires 11/30/2026 ASN 2023-AWP-18952-OE. The carrier's construction schedule is slated for February 2027. Re-filing for an updated FAA DNH. TMO to upgrade existing antennas behind a screening that makes up the overall structure height at 44 feet AGL per the 1A with top of antennas at 43 feet AGL. T-Mobile requests the structure is to remain with no marking and lighting required."

Screening a structure of your own?
Check Part 77 and the tower's line of sight before you file
