STI-CO

What STI-CO does

STI-CO Industries, LLC is a privately held U.S. manufacturer founded in 1967 and headquartered in Orchard Park, New York, that designs and builds custom RF antenna systems and rugged interconnect solutions for mission-critical mobile communications. Its product portfolio spans six market-aligned lines — Covert Operations, Public Safety, Tactical/Military, Commuter/Freight Rail, Commuter Bus, and Interconnect Systems (cable assemblies, wire harnesses, over-molded assemblies) — covering frequencies from VHF through UHF, 7/800 MHz, LTE, 5G NR FR1, Wi-Fi 6e, GPS/GNSS, and CBRS/Band14. Technical differentiators include the trademarked Flexi-Whip™ nickel-titanium flexible mast construction, a patent-pending covert sun-shade antenna, advanced over-molding and sealing for harsh-environment cable assemblies, and compliance with MIL-STD-810, AREMA, IPX7, and SAE J1455 environmental standards.

The company monetizes primarily through hardware sales of antennas and cable assemblies, supplemented by custom engineering and build-to-print manufacturing services. Pricing is account-gated on a B2B e-commerce storefront with multi-year contracts and quote-based terms. Go-to-market is sales-led, combining direct sales, manufacturer representatives (e.g., WLM Component Sales in New England), and a network of authorized distributors across the U.S. (BearCom, Talley, TESSCO on GSA, rf Services), Canada (Bell Mobility, DYPLEX, Kerr Industries, Traeger), and Israel (Commtel). End customers are defense and military programs, public safety agencies (police, fire, EMS), rail and transit operators (commuter, freight, bus), and select commercial/industrial buyers. STI-CO is AS9100D- and ISO 9001:2015-certified, ITAR registered, SAM registered, and RoHS and IPC/WHMA-A-620 compliant, positioning it as a qualified supplier for U.S. government and defense programs.

The firm is family-owned with no disclosed external private equity or venture backing and no subsidiaries. Leadership includes President Kyle Swiat and CEO Mike Stien. The company has remained continuously operating for more than 50 years with no public funding history, no M&A activity, and no disclosed leadership transitions in the available material, while continuing active product development (notably a January 2025 expansion of cable/harness capabilities and 5G Ultra Wideband product launches) and ongoing patent activity.
