We didn't cut any corners! Only premium materials are used throughout the system. The AI tubing is Made in the USA, double-dipped, double-walled, high-grade 6000 series aircraft-grade aluminum we are very proud of, 2-inch OD or 2.25-inch OD top to bottom, industrial-strength fiberglass insulators at the feed and base, stainless steel hardware throughout, and a 3kW custom made RF Choke to help complete your "floating" antenna system! This isn't your typical Amateur claim where "Rated 80MPH" means it folds at 50MPH. A Structural Analysis was completed properly.
