Should the federal government avoid no-bid infrastructure contracts on properties owned by political figures?
On September 1, 2026, the Department of Justice awarded a $72,525 no-bid contract to NAMSI LLC for antenna installations. The FBI is placing this equipment on Trump Plaza in New Rochelle and Trump World Tower in New York City to address ongoing transmission issues.
Why it matters
These installations mitigate signal interference caused by the 2015 AWS-3 spectrum auction. The agency identifies these specific high-rise locations as optimal sites for maintaining its ACRx surveillance system.
The project utilizes the 1755-1780 MHz spectrum band for DOJ video surveillance links. The FBI plans to conduct six to ten installations annually, aiming to resolve coverage gaps at 35 to 45 total sites nationwide.
The players
FBI
The Federal Bureau of Investigation is the domestic intelligence and security service of the United States.
NAMSI LLC
NAMSI is a private entity contracted to handle site access and antenna installations for federal agencies.
The Trump Organization
The Trump Organization is a multinational conglomerate that owns and manages various commercial and residential properties.
Drug Enforcement Administration
The DEA is a federal law enforcement agency tasked with combating drug smuggling and distribution within the United States.
The details
The agency utilizes no-bid contracts to secure roof access through property managers at essential locations. While the Trump Organization manages Trump World Tower, it ceased management of Trump Plaza in 2021.
Timeline
The FCC auctioned AWS-3 airwaves in 2015.
The DEA began contracting with NAMSI for Trump World Tower in 2020.
The Trump Organization stopped managing Trump Plaza in 2021.
The FBI installed an ACRx antenna at Trump World Tower in 2022.
The DOJ awarded the NAMSI contract on September 1, 2026.
The Tech Race
This effort to upgrade surveillance infrastructure highlights the ongoing challenges federal agencies face when reconfiguring legacy systems to operate alongside commercial spectrum. It marks a shift toward securing specialized high-altitude access to overcome technical hurdles in dense urban environments.
Residents of the affected properties or the surrounding neighborhoods should be aware of continued federal equipment maintenance on building rooftops. These installations are focused on optimizing existing government surveillance networks rather than altering commercial consumer connectivity.
The takeaway
Federal agencies often rely on existing private commercial real estate to maintain essential public safety infrastructure. Property managers and residents of high-profile buildings should expect occasional coordination with federal entities for specialized equipment maintenance.
