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

"Updating frequencies and adding CBAND/DoD frequencies to existing structure with existing ASN 2013-AGL-8116-OE."

Screening a structure of your own?

Check Part 77 and the tower's line of sight before you file

LOS Analyzer screens a proposed structure against FAA Part 77 surfaces and the control tower's sightline to the runway, terrain-aware, in minutes. It is a preliminary screening — not an FAA determination and not a substitute for a licensed engineering review.
