Installing an outdoor omnidirectional antenna (Canada)

When installing an outdoor omnidirectional external antenna, ensure you follow these guidelines:

• Locate the antenna on the external wall of the building.

Note: You must install the antenna on a vertical surface.

• Keep the outdoor omnidirectional external antenna as close as possible to the base station. The

base station itself must always be located inside the building.

• The recommended installation height is 4 m (13 ft) to 5 m (16.5 ft) above ground level.

• Always install a surge protector between an outdoor omnidirectional external antenna and a

base station.

Note: The connector on the outdoor omnidirectional external antenna is a TNC female

connector. To connect the antenna, you need an adapter to connect the TNC connector to the

BNC coaxial cables or a coaxial cable with a TNC male connector on one end and BNC male

connector on the other end.

Caution: Fit lightning protection to the antenna if appropriate.

See “Installing a lightning surge protector (Canada)” on page 40 for more information.

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 coaxial cable of an

outdoor antenna.

• Always install the antenna at the cable entry point into the building.

• Connect the lightning surge protector to ground before connecting the coaxial cable.
