3.5 Antenna Installation
The WL2400 has been FCC Certified for use with the YDI Model AMP2440P and a variety of outdoor
antennas.
Table (1) shows the FCC approved external antennas that can be used with and without the YDI
AMP2440P. The AMP2440P and the YDI WL2400 WLAN cards must be professionally installed when
used with an outdoor antenna or amplifier. It is the responsibility of the installer to ensure that when used
in the United States (or where FCC rules apply) under Part 15 regulations, only these configurations are
used.
Figure (1) shows the antenna cabling diagram for connection to an external antenna. Note that a special
adapter cable is needed from the WLAN card to the transmission line to the antenna.
3.6 RF Exposure Safety Information
All antennas must be installed so that no person will be closer than the distances specified as outlined in
the following table:
