The GigAccess™ was designed to work with co-located antennas. That means that two antennas
can be connected. The minimum distance between the two antennas should be 20 cm. The two
antennas should be of the same type (Directional Flat Panel Antenna, or Base Station Antenna or
Parabolic Dish). The main idea is to utilize two polarizations: one antenna in vertical polarization
and the other in horizontal polarization. The user will select the antenna in need. Omni antennas
are not relevant for co-location. Only the selected antenna is operational. Configuration is done
with the advanced window of the Unit Manager Tool (See paragraph 10.4.1). If the “External
Antenna Select” check box is selected the detached antenna is selected, otherwise the integrated
antenna is selected.
Note: The FCC 15.203 requirement prohibits the connection of detached antennas with standard
N-type connectors. In order to meet this requirement, the detached antenna connectors
provided on GigAccess™ models (with no integral antenna) are non-standard, TNC
connector. Only professional technician will perform the installation.
2.4.3.3. Guidelines for Selecting Outdoor Location
Select the appropriate locations for the outdoor unit using the following guidelines:
• The outdoor unit can be pole or wall mounted. Its location should allow easy access to the
unit for installation and testing.
• The AU should be installed where it provides coverage of all SUs in the area it is intended
to serve. The higher the AU or its detached antenna, the better coverage it can provide.
• When using a detached antenna, the AU should be installed as near as possible to its
antenna.
Note: The distance between any two antennas should be at least 50 cm.
Warning! For a base station or any installation consisting of more than one outdoor unit (AU or
SU) the safety distance for all persons should be at least 2 meters.
