Installing antennas (United States of America)
The following points cover special information about installations in the United States of America.

to join with the connector on the base station.
• Cables are not supplied with outdoor antennas.
Before You install an outdoor antenna (USA)
Before you install an outdoor antenna, check the following points:
• Locate the antenna on the external wall of the building.

station must always be inside the building. The recommended installation height for the
antenna is 13 to 16 ft. above ground.
