It is unlikely to happen but since the LTE base station is very sophisticated equipment so we would recommend you to test it on the ground to make sure everything is functioning before install on the tower. The operator must prepare external against lightning protector to protect the GPS, external antenna and RJ-45 port. Grounding Notes:
The ground wire adopts yellow-green wire that is no smaller than 16 mm. Grounding principle: as near as possible. The base station connects to the reliable outdoor grounding point (earth) through one ground screw. The connection of the grounding points and the ground bar need to be tight and reliable. Rustproofing the terminals is required. This can be done with rust preventing paint, anti-oxidation coatings, grease, etc. 2.6 Weatherproof Protection The Nova-243 adopts cold shrink tube for weatherproof protection. Before installing the cold shrink tube, clean up the interface first. The weatherproof protection steps are as follows:
1. Insert cable into cold shrink tube. 2. Tighten the connector. 3. Push the cold shrink tube to the top joint and pull out the strip. 4.

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. 17 Nova-243 Outdoor LTE TDD Base Station Installation Guide Figure 3-6 Omnidirectional Antenna Installation (2) 3.7.2 Install Directional Antennas 1. First, assemble the antennas, as shown in Figure 3-7. Figure 3-7 Assembling Procedure of Directional Antennas 2.
