2.4 Installation Guidelines
This section describes the installation guidelines and the various considerations
that must be taken into account when planning the installation.
2.4.1 Location of the Unit and Antenna(s)
• The unit can be placed on a shelf, or can be attached to the ceiling or a wall
using a mounting bracket. The unit should be installed as near to the
antenna(s) as possible to minimize loss of RF power in the cable(s).
• Keep the units well away from sources of heat, such as radiators, air-
conditioners, etc.
2.4.2 Location of the Antenna(s)
• Any physical object in the path between two units can cause signal
attenuation. Common obstructions are buildings and trees. If a unit’s
antenna is installed indoors, the walls and/or windows between the two
sites are physical obstructions. If the antenna is positioned outdoors, any
buildings or other physical structure such as trees, mountains or other
natural geographic features higher than the antenna and situated in the path
between the two sites can constitute obstructions.
• Install indoor antennas as close as possible to a window (or wall if a
window is not accessible) facing the required direction. Avoid metal
obstacles such as metal window frames or metal film anti-glare windows in
the transmission path. Install outdoor antennas high enough to avoid any
obstacles, which may block the signal.
• Position the antennas clear of metal furniture and away from moving metal
objects such as metal fans or doors.
• For best performance, position the antennas clear of radiation sources that
emit in the 2.5 - 2.7 GHz frequency band, such as microwave ovens.
