Caution Do not locate the antenna near overhead power lines or
other electric light or power circuits, or where it can
come into contact with such circuits. When installing
the antenna, take extreme care not to come into contact
with such circuits, as they may cause serious injury or
death. For proper installation and grounding of the
antenna, please refer to national and local codes (e.g.
U.S.: NFPA 70, National Electrical Code, Article 810,
Canada: Canadian Electrical Code, Section 54).
