Installing a Reflector Dish
The internal patch antenna of the module illuminates the Passive Reflector Dish from an offset position.
The module support tube provides the proper angle for this offset.
Both Modules Mounted at Same Elevation
For cases where the other module in the link is mounted at the same elevation, fasten the mounting
hardware leg of the support tube vertical for each module. When the hardware leg is in this position
• the reflector dish has an obvious downward tilt.
• the module leg of the support tube is not vertical.
For a mount to a non-vertical structure such as a tapered tower, use a plumb line to ensure that the hardware
leg is vertical when fastened. Proper dish, tube, and module positions for a link in this case are illustrated in
Figure 142. The dish is tipped forward, not vertical, but the focus of the signal is horizontal.
