3. To prevent undue cable stress on the co-axial cable, secure it to
the mounting surface with a clamp.
4. Connect the external antenna to the appropriate Base Station
radio.
Note: The length of the co-axial cable must not exceed 10 m.
When installing an outdoor omni-directional external antenna:
• Locate the antenna on the external wall of the building.
Note: The antenna must be mounted on a vertical surface.
• Keep the outdoor omni-directional external antenna as close as
possible to the Base Station serving it (the Base Station must be
inside). The recommended mounting height is 4 to 5 m above
ground level.
• Always install a surge protector between an outdoor
omnidirectional antenna and a Base Station.
Note: The connector on the outdoor omni-directional antenna is
a TNC female connector, so you need an adapter to
connect it to the standard BNC co-axial cables needed for
the surge protector and the Base Station. You can also use
a co-axial cable with a TNC male connector on one end
and BNC male connector on the other end.
!
Fit lightning protection to the antenna if appropriate.
See "Installing a lightning surge protector."

Important points to remember:
• Do not install the external antenna or the lightning surge protector
during an electrical storm.
• Always turn off the Base Station power before connecting the co-
axial cable of an outdoor external antenna.
• Always install the antenna at the cable entry point into the
building.
• Connect the lightning surge protector to ground before connecting
the co-axial cable.
