Installing antennas (Canada)

There are three types of external antennas available in Canada:

• indoor directional antenna (“Installing an indoor directional antenna” on page 36)

• indoor omnidirectional antenna (“Installing an indoor omnidirectional antenna (Canada)” on

page 37)

• outdoor omnidirectional antenna (“Installing an outdoor omnidirectional antenna (Canada)”

on page 38).

Each type of installation requires a specific installation technique. As well, you must install a

lightning surge protector for every outdoor antenna installed (“Installing a lightning surge

protector (Canada)” on page 40).

Outdoor requirements

Before you install the antenna, ensure that your plan meets the following requirements:

• If you are installing an outdoor antenna on a metal surface greater than 18 cm (7 in.) in

diameter, position the antenna perpendicular to the surface.

• When running the coaxial cable inside or outside, be careful not to damage the cable, which

affects its performance. The minimum recommended bending radius is 20 mm (0.8 in.).

• Always ensure that the antenna is clear of any adjacent obstruction or metal objects. If you use

more than one outdoor antenna at a cell center, separate the antennas at by least 0.5 m (20 in.)

to avoid radio interference problems.

• Use RG-58/U coaxial cables to connect the antennas to the base stations.

CAUTION: Use only passive antennas to connect to the Companion base stations.

The coaxial cable you use to connect the external antenna to a Companion base station must have

an impedance of 50 ohms.
