4th step: Determining what concrete blocks are re-
quired
Based the maximum gust speed, the number and
size (10 kg) concrete blocks required can be
determined for the air-termination rod used. The value
in the tables must lie above the maximum gust speed
for the location.15: Number OBO concrete blocks required
