Global Tower Holdings LLC

Global Tower Holdings LLC, doing business as Global Tower, LLC, operates as a Boston-based radio antenna site lessor providing communications infrastructure to the U.S. Department of State and the Drug Enforcement Administration as a prime contractor on full-and-open purchase orders. The company is a child entity of American Tower, L.P., a publicly traded communications infrastructure parent, and competes without set-aside designation across all recent federal work.

Global Tower Holdings LLC supplies radio antenna site leases and related tower infrastructure access — a narrowly specialized capability anchored in two federal customers. The Department of State's Bureau of Diplomatic Security accounts for eleven awards totaling $564 thousand in combined potential value, centered on recurring annual leases for the Alliance Capital Building in New York. The Drug Enforcement Administration has placed seven awards worth $224 thousand combined, also for antenna site leases and equipment access, predominantly in New York. Representative work includes a five-year firm fixed-price purchase order awarded January 1, 2026, by the State Department for $248,589.36 extending through December 31, 2030; annual renewal leases from both agencies spanning 2021 through 2026, typically priced between $37 thousand and $45 thousand per performance period; and a $22,479.91 DEA lease covering July through December 2023.

The vendor's customer concentration is extreme and stable. The two federal customers — State and DEA — account for 100% of recent awards and combined potential value, with State Diplomatic Security capturing 71% of the dollar share ($564 thousand of $788 thousand). Award volume has remained flat at one to two awards per year across 2022–2026, with eighteen total awards in the source snapshot and combined potential value of $788 thousand. No recompete cliff is material; the vendor's award cycle is annual renewal-based, with rolling completion dates that distribute recompete exposure evenly across the calendar rather than clustering into a single near-term window.

The vendor operates exclusively as a prime contractor (100% of awards) with no subcontract footprint. Its NAICS and PSC portfolio reflects the narrowness of the business: Power and Communication Line and Related Structures Construction and Radio and Television Broadcasting and Wireless Communications Equipment Manufacturing dominate the category breakdown, with Antennas, Waveguides, and Related Equipment and Lease/Rental of Other Non-Building Facilities appearing across seven awards each. As a subsidiary of American Tower, L.P., Global Tower Holdings LLC functions as a specialized leasing vehicle for the parent's New York communications infrastructure assets, with federal revenue accounting for a small fraction of the consolidated American Tower enterprise.
