Assembling the air-termination rod
Note!
To determine how many concrete bases must be used in the isFang
air-termination rod system, we recommend asking a planning office to
carry out the static calculations. You can find further information on wind
speed zones in the OBO TBS lightning protection guide and national
directives.
