ODU must be grounded to the supporting structure. A surge suppression unit must be installed on the outside of the building.](https://usermanual.wiki/Cambium-Networks/50450M.User-Manual/User-Guide-3232538-Page-12.png)
![Chapter 6: Installation Mount the ODU, LPU and surge suppressor Page 6-13 The distance between the ODU and Gigabit Surge Suppressor should be kept to a minimum. The drop cable must not be laid alongside a lightning air terminal. All grounding cables must be a minimum size of 10 mm2 csa (8AWG), preferably 16 mm2 csa (6AWG), or 25 mm2 csa (4AWG). Grounding cable requirements When routing, fastening and connecting grounding cables, the following requirements must be implemented: Grounding conductors must be run as short, straight, and smoothly as possible, with the fewest possible number of bends and curves. Grounding cables must not be installed with drip loops. All bends must have a minimum radius of 203 mm (8 in) and a minimum angle of 90° (Figure 51). A diagonal run is preferable to a bend, even though it does not follow the contour or run parallel to the supporting structure. All bends, curves and connections must be routed towards the grounding electrode system, ground rod, or ground bar. Grounding conductors must be securely fastened. Braided grounding conductors must not be used. Approved bonding techniques must be used for the connection of dissimilar metals. Figure 51 Grounding cable minimum bend radius and angle Caution Do not attach grounding cables to the ODU mounting bracket bolts, as this arrangement will not provide full protection.](https://usermanual.wiki/Cambium-Networks/50450M.User-Manual/User-Guide-3232538-Page-13.png)

![Chapter 6: Installation Installing external antennas to a connectorized ODU Page 6-36 4 Choose the best mounting location for your particular application. Note Use the embedded spectrum analyzer or a commercial analyzer to evaluate the frequencies present in various locations. OFDM APs need not be mounted next to each other. They can be distributed throughout a given site. However, the 90° offset must be maintained. If you want to collocate these APs with PMP 100 Series APs of the 5.4-GHz frequency band range, plan to allow at least 25 MHz of separation between their center channels. 5 Secure a ground strap to the ground lug on the back of the AP. 6 Secure the ground strap to the pole, tower, or other trusted ground. 7 The bracket of the standard antenna has provision for measured down tilt. The recommended practice is to use one of the many radio analysis and mapping tools or on-line tools to calculate down tilt based on antenna height above the service area. The proper angle of tilt can be calculated as a factor of both the difference in elevation and the distance that the link spans. Even in this case, a plumb line and a protractor can be helpful to ensure the proper tilt. This tilt is typically minimal. The number of degrees to offset (from vertical) the mounting hardware leg of the support tube is equal to the angle of elevation from the lower module to the higher module (<B in the example provided in Figure 44).](https://usermanual.wiki/Cambium-Networks/50450M.User-Manual/User-Guide-3232538-Page-36.png)

![Chapter 6: Installation Supplemental installation information Page 6-65 Creating a drop cable grounding point Use this procedure to connect the screen of the main drop cable to the metal of the supporting structure using the cable grounding kit (Cambium part number 01010419001). To identify suitable grounding points, refer to Drop cable grounding points on page 3-14. 1 Remove 60 mm (2.5 inches) of the drop cable outer sheath. 2 Cut 38mm (1.5 inches) of rubber tape (self-amalgamating) and fit to the ground cable lug. Wrap the tape completely around the lug and cable. 3 Fold the ground wire strap around the drop cable screen and fit cable ties.](https://usermanual.wiki/Cambium-Networks/50450M.User-Manual/User-Guide-3232538-Page-65.png)

Wrap the layers in alternate directions (top to bottom, then bottom to top). The edges of each layer should be 25mm (1 inch) above (A) and 25 mm (1 inch) below (B) the previous layer. 9 Prepare the metal grounding point of the supporting structure to provide a good electrical contact with the grounding cable clamp. Remove paint, grease or dirt, if present. Apply anti-oxidant compound liberally between the two metals. 10 Clamp the bottom lug of the grounding cable to the supporting structure using site approved methods. Use a two-hole lug secured with fasteners in both holes. This provides better protection than a single-hole lug.](https://usermanual.wiki/Cambium-Networks/50450M.User-Manual/User-Guide-3232538-Page-67.png)
![Chapter 6: Installation Supplemental installation information Page 6-68 Attaching and weatherproofing an N type connector The following procedure should be used to weatherproof the N type connectors fitted to the connectorized ODU (AP/SM/BH) and antenna. This procedure must be followed to ensure that there is no moisture ingress at the radio ports. Failure to properly seal N-type antenna connectors can result in poor link performance or complete loss of radio communication. Note Cambium recommends to assemble the antenna, attach the ODU and cabling, and to seal the RF connections before installing the unit at the deployment site. Note N type connectors should be tightened using a torque wrench, set to 15 lb in or 1.7 Nm. If a torque wrench is not available, N type connectors may be finger tightened. Use this procedure to weatherproof the N type connectors fitted to the connectorized ODU and external antenna (if recommended by the antenna manufacturer). 1 Ensure the connection is tight. A torque wrench should be used if available: 2 Wrap the connection with a layer of 19 mm (0.75 inch) PVC tape, starting 25 mm (1 inch) below the connector body. Overlap the tape to half-width and extend the wrapping to the body of the LPU. Avoid making creases or wrinkles:](https://usermanual.wiki/Cambium-Networks/50450M.User-Manual/User-Guide-3232538-Page-68.png)
