IMPORTANT!
Connectorized antennas require professional installation.
The professional installer is responsible for
• selection of an antenna that the regulatory agency has approved for use with the
Cyclone 900-MHz AP and SM.
• setting of the gain consistent with regulatory limitations and antenna
specifications.
• ensuring that the polarity—horizontal or vertical—is identical on both ends of the
link. (This may be less obvious where an integrated antenna is used on one end
and a connectorized on the other.)
• use of moisture sealing tape or wrap to provide long-term integrity for the
connection.
