2.6.3 Rooftop Installation
WARNING! Rooftop antenna installations are extremely dangerous! Incorrect
installation may result in death, serious injury and/or damage. Such installations
should be performed by professional antenna installers only!
Rooftop installations offer several advantages:
•1 Increased antenna range.
•2 Fewer obstacles in path.
•3 Improved performance due to greater height.
•4 Reduced multipath problems.
2.6.4 Antennas for Outdoor Applications
The BreezeNET DS.11 series can be used in point-to-point or point-to-multipoint configurations.
Point-to-Point
The BU-DS.11/RB-DS.11 must be equipped with one or two directional antennas. The necessary
antenna gain depends on the required range and performance.
Point-to-Multipoint
Setting up a point-to-multipoint link requires the use of a BU-DS.11 equipped with omni-
directional antennas and at least two RB-DS.11 units equipped with high-gain directional antennas.
Note: The FCC 15.203 requirement prohibits the connection of external antennas with standard N-
type connectors. In order to meet this requirement, the external antenna connectors provided on
DS.11D models (with no integral antenna) are non-standard, featuring left-handed (counter-
clockwise) rotation.
2.6.5 Antenna Alignment
Low gain antennas do not require alignment due to their very wide radiation pattern. High gain
antennas have a narrow beamwidth necessitating an alignment procedure in order to optimize the
link.
Check antenna alignment by using the RSSI bar on the bottom panel of the
RB-DS.11 bottom panel.

To perform antenna alignment:
1. Assemble antennas according to the assembly instructions included with the antenna set.
