Antenna Installation Warning
1. All antenna installation and servicing is to be performed by
qualified technical personnel only. When servicing the antenna, or
working at distances closer than those listed below, ensure the
transmitter has been disabled.
Output is measured at the antenna terminal of the transmitter. The
antenna(s) used for this transmitter must be fixed-mounted on
outdoor permanent structures to provide the minimum separation
distances described in this filing for satisfying RF exposure
compliance requirements. When applicable, RF exposure
compliance may need to be addressed at the time of licensing, as
required by the responsible FCC Bureau(s), including antenna
co-location requirements of
§
1.1307(b)(3).
2. Typically, the antenna connected to the transmitter is a directional
(high gain) antenna, fixed-mounted on the side or top of a building,
or on a tower. Depending upon the application and the gain of the
antenna, the total composite power could exceed 200 watts EIRP.
The antenna location should be such that only qualified technical
personnel can access it, and that under normal operating conditions
no other person can touch the antenna or approach within
3.05
meters of the antenna.
