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.
