Installation
User's Guide 2-10 BreezeNET BU-DS.11/RB-DS.11
When installing a single antenna, modify the transmit diversity option to either antenna
1 or antenna 2, according to the antenna being used (refer to page 3-9).
2.6.7 Antenna Polarization
Antenna polarization must be the same at either end of the link. In most applications,
the preferred orientation is vertical polarization. Above-ground propagation of the
signal is better when it is polarized vertically. To verify antenna polarization, refer to
the assembly instructions supplied with the antenna set.
2.6.8 Antenna Seal
When using outdoor antennas, you must seal unused antenna connectors against rain
with the antenna connector seals provided with the unit.
2.6.9 Cell Size
Cell size is determined by the maximum possible distance between the BU-DS.11 and
the RB-DS.11 unit, usually related to point-to-multipoint installations using external
antennas. For open outdoor areas with an unobstructed line of sight between the BU-
DS.11 and the RB-DS.11 units, the suggested maximum distance is up to 7KM (4.3
miles).
2.6.10 Link Distance
For open outdoor areas with an unobstructed line of sight between the BU-DS.11 and
the wireless bridge, the suggested maximum distance is:
BU-DS.11 with external antennas up to
24Km (15 miles) in the USA
Up to 15Km in Europe
Note: The maximum distance of 24Km/15 miles is achieved using 24 dBi antennas.
The maximum distance of 15Km is achieved using 18 dBi antennas.
