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