3.2.2. Add extra lightning rod
This is a sample of adding lightning rod with some reason:
It installed beside a chimney, 8 meters away from the radar. In this case the chimney is fixed,
therefore it is better to install a new lightning rod as shown in the figure 4.
The weather radar will be covered by combination with new and existent lightning rods.
Height requirement for the new lightning rod for each LPL are shown in the table 9Table. The
length will be selected depends on the height limitation, therefore it is better to use a longer one.
Somehow in this case, it is not enough for protecting the weather radar from lightning.
In order to provide a solution for this situation, we suggest adding a new lightning rod to install
nearby.
Basically a newly prepared rod should be designed as long as possible, but it needs to think
about the height limitation either.
