3.2. Modification Plan
As shown in Table A-6 the current condition is not enough to protect the weather radar. We would
propose the following modification plan to protect the weather radar.
3.2.1. Extend existing lightning rod
We installed new lightning rod to protect the radar, but it is
insufficient
due to some restrictions. Now
we are considering how to adapt the LPL by extending the lightning rod.
As shown in Table 8 we need to extend the rod at least 5.1 m from the current length, but it is not
allowed due to site height restrictions.
