Nova-243 Outdoor LTE TDD Base Station Installation Guide 17 Install Antenna Feeder System 3.7There are two kinds of outdoor antennas, omnidirectional outdoor antennas and directional outdoor antennas, whose installation will be introduced in the following, respectively. 3.7.1 Install Omnidirectional Antennas One should pay attention to the followings while installing the omnidirectional outdoor antenna:  The diameter of the pole for omnidirectional outdoor antennas is required to be 35mm ~ 50mm. A typical case is to use the 50mm-diameter round-steel-made pole (with details depending on the specific antenna type).  Make sure that the top of pole and the clamp beneath the antenna are at the same level, after installing the omnidirectional outdoor antenna on the pole.  Make sure that the antenna is high enough to meet the coverage requirement, and that the antenna top falls within the 45 degrees safety angle towards the lightening rod, as shown in Figure 3-5. 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. Figure 3-5 Omnidirectional Antenna Installation (1) In case is impossible to install an independent lightning rod due to environmental limitations, the installation method shown in Figure 3-6can be used. Be aware that the pole supporting the lightening rod should be kept at least 1m away from the omnidirectional outdoor antennas.
