The kit contains everything necessary to build a bracketed tower including the tower sections, mounting brackets, and all attachment hardware. All steel parts of the 4.618.BSTG.030 are completely hot-dip galvanized per ASTM A153. Please consult the Tower Selection Guide below to determine if this tower will support your loading requirements.BRBRThe loading capacity of the Trylon STG Bracketed Towers is dependent upon the tower's cantilever length which must be calculated as the overall tower height less the height of the house bracket attachment. Please consult the Tower Selection Guide attachment to determine if the tower height you have selected will support your antennas and wind pressure.BRBRTESSCO recommends that you complete a Tower Design Questionnaire so we can make sure you are getting the right tower for your application. TESSCO assumes no risk for any tower purchased without a completed TESSCO Tower Design Questionnaire.
