Installation Guidelines

This section describes the installation guidelines and the various
considerations that must be taken into account when planning the
installation.
Location of the Unit
The unit can be placed on a desktop or a shelf, or can be attached to
a wall.
The unit should be installed as near as possible to the antenna. The
RF cable connecting the unit to the antenna should be as short as
possible to guarantee minimum power loss.
The location of the Subscriber Unit should take into account its
connection to a power outlet and the user's data equipment.
Keep the units well away from sources of heat, such as radiators,
air-conditioners, etc.
Location of the Antenna
The antenna should be pole mounted on the rooftop or on a
sidewall. It should be installed where it can be directed towards the
location of the Cell Extender or Access Unit. Any physical object in
the path between the unit and the Cell Extender/Access Unit other
than foliage should be avoided. Any buildings or other physical
structure such as hills or other natural geographic features higher
than the antenna and situated in the path between the two sites can
constitute obstructions.
WARNING
It is the responsibility of the professional installer to ensure that when using the
outdoor antenna kit, that only this antenna provided with the subscriber unit is
used along with the minimum cable lengths provided. The use of any antenna
other than those listed is expressly forbidden in accordance to FCC rules CFR47
part 15.204.

Antenna Polarization

Antenna polarization must be the same at both ends of the link. The
antenna can be mounted to provide either vertical or horizontal
polarization. To verify polarization of the antenna, refer to the mounting
instructions in Appendix B.
