Recommendation

No objection to the final design for modifications to the existing AT&T cellular antenna array on the roof of the DOI headquarters building, per materials received 1 June 2023. Scope of work includes the removal of 3 existing panel antennas and the installation of 2 new enclosed spherical antennas at the mechanical penthouse. 13 existing remote radio heads (RRH) would be removed, 4 would be relocated to another sector, and 17 new RRHs would be installed at the mechanical penthouse. New antenna enclosures would be painted to match the penthouse.
