T750 & T750SE, Access Point Installation Addendum
When the frequency band 5150 – 5250 MHz is used outdoors in the U.S.A, the FCC mandates that the energy radiated above 30° from the horizon
remains below 21 dBm EIRP. This can be maintained during installation using the following guidance.
When the device is installed level to the horizon, (i.e. – device perpendicular to the surface of the earth, antenna radome pointing horizontal, parallel to
the earth), the device operates in compliance with FCC rules without any adjustment of output power.
T750 & T750SE – Antennas
When the device is installed outdoors at an angle above the horizon, it may be
necessary to reduce output power to insure the energy radiated
above 30° from the horizon remains under 21 dBm EIRP. Please see
table and elevation plots below.
