Greater distances increase probability for line-of-sight blockages: As the distance between buildings
increases, there is a greater likelihood of objects blocking the line-of-sight between BL sites. When
planning applications with greater distances, avoid problems caused by new construction or tree growth by
placing the antenna higher. This decreases the likelihood for line-of-sight blockages over time but
increases the length of Ethernet cable required.
If the structure has an eave, RMG recommends that you not place the BPU so high into the eave that the
roof blocks a line-of-sight view to the distant BridgeLINK-Pro™. Before securing the BPU to its mounting
structure, verify that you can see the distant BPU and that the line-of-sight is clear of all obstructions.
Cabling Cabling
The BL-Pro comes with 50 feet of pre-installed Ethernet Cabling. This cabling is connected to the PoE
injector. Other lengths are available upon request.
Grounding Considerations Grounding Considerations
RMG recommends proper grounding of the BridgeLINK -Pro as described in mounting hardware
installation instructions and as required by local ordinance. Connect any metallic mounts supporting the
BPU to a ground rod driven a minimum of 10 feet into the soil. Make sure the BPU is at least 6 feet below
the top of the mast. For more information, follow Section 810 of the National Electrical Code. Use UL-listed
ground clamps and lugs.
Securing Securing the Unit (Wind loading) the Unit (Wind loading)
Wind can cause an antenna to come out of alignment and degrade the data link. This will show up as
intermittent or degraded performance or even as no link at all. While the shape of the BPU will minimize
wind load, it is important to securely install the BPU and fasten it tightly.
