Before Installing the
Antennas
The following considerations should be taken
into account before installing the antennas.
Cable Length Limitation (1) — The Ethernet
cable between the antenna and the IPLink
must never exceed 300 feet (90 meters).
Cable Length Limitation (2) — The PoE de-
vice should be mounted no more than 2 feet
(1/2 m) from the IPLink module.
Wall Jack Required — A wall jack must be
located within 1.5 feet (460mm) of the UPS.
Battery Backup Required — To protect the
antenna against a power surge and electrical
fluctuations, the PoE device should be con-
nected to the BATTERY SIDE of the Battery
Backup (UPS).
Protective Case Suggested — The PoE device
& battery backup (UPS) are not dust and
moisture proof. They should either be located
in a clean environment or placed in a dust &
watertight enclosure such as the optional
Medium White ABS Box.
Good Line of Sight Required — All anten-
nas must be in direct line of sight with the
AP antenna. This direct line of sight is only
possible when all antennas have about the
same height above mean-sea-level. The area
around the visual line of sight must also be
clear from obstacle or else signal strength will
degrade. To increase the transmission range
of an antenna, raise it further above the roof
by mounting it on a pole.
Distance from Electrical Lines — The antenna
should be mounted at least 16 feet (5 m)
away from electrical lines.
