5.3.2. 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:
• Increased antenna range.
• Less obstacles in path.
• Improved performance due to greater height.
• Reduced multipath problems.
5.3.3. Antennas for Outdoor Applications
The BreezeNET PRO.11 Series can be used in point-to-point or point-to-
multipoint configurations.
5.3.3.1 Point-to-Point
A point-to-point link is based on the use of one Access Point with external
antennas (AP-10D or AP-10DE) and one adapter (SA-10/40D, WB-10D or
WB-10DE). The AP and the WB must be equipped with one or two
directional antennas. The necessary antenna gain depends on the required
range and performance.
5.3.3.2 Point-to-Multipoint
Setting up a point-to-multipoint link requires the use of an AP-10D
equipped with omni-directional antennas and a remote WB-10D (or SA-
10/40D) equipped with high-gain directional antennas.
5.3.3.3 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.
