Warning Antenna Installation Instructions RF Exposure Limits SX1126 only.
The SX1126 transverter with its integral antenna is to be used in point-to-point
applications only. The SX1126 shall be professionally installed on a permanent
structure for outdoor operation.
The installer shall mount the SX1126 so as to comply with the limits for human exposure to radio
frequency (RF) fields per paragraph 1.1307 of the Federal Communications Commission (FCC)
Regulations. The FCC requirements incorporate limits for Maximum Permissible Exposure (MPE)
in terms of electric field strength, magnetic field strength, and power density.
The MPE distance for the SX1126 is 1.5 meters (5 ft). This is the minimum distance that must be
under all conditions of operation between the antenna and any area where persons may have access,
including rooftop walkways, sidewalks, as well as through windows and other RF -transparent
areas behind which persons may be located

In addition to MPE, FCC Rules limit power delivered to the antenna based on maximum permissible EIRP, for
both in-band and out-of -band emissions. The professional system installer is responsible for complying with
the settings in Table 3 below.
