that the antenna top falls within the 45 degrees safety angle towards the lightening
rod, as shown in Figure 3-3. In principle, no lightening rod can be welded to pole (no
metal object is allowed within 1m of the horizontal direction of the omnidirectional
antennas), when installing the omnidirectional antennas. Instead, an independent
lightening rod should be settled between the two poles, where the lightening rod
must be high enough to keep all antennas under its protection cover.
In case is impossible to install an independent lightning rod due to environmental
limitations, the installation method shown in Figure 3-4 can be used. Be aware that the
pole supporting the lightening rod should be kept at least 1m away from the
omnidirectional outdoor antennas.
