Changes and Impact of ANSI/TIA-222-H on Existing and New Broadcast Infrastructure

ANSI/TIA-222-H is the latest revision of the 222 design standard from TIA, effective January 1, 2018. In a little less than 2 years, the updated standard has had a profound impact on structural design, evaluation and maintenance of tower infrastructure. These changes include more efficient evaluation of wind, ice and earthquake loads, greater clarity around mounts and antennas designs and focus on existing infrastructure, specifically with respect to inspection, anchor evaluation and construction expectations. This paper / presentation will highlight these changes, compare to earlier revisions and discuss implementation / adoption nationwide.
