Any antenna from a reputable manufacturer with desired bandwidth, gain/pattern coverage, and have
an input surge impedance of approximately 50 ohms can be used with the Xeta4. Since professional
installation is required, standard RF connectors are used. Adapters or custom coaxial cables may be
required to connect the radio output connector to the desired antenna, provided the appropriate
requirements are met.

The RF Exposure section has more power settings vs. antenna gain. The 500W ERP is the maximum
allowed by the FCC. Other installations may require different settings depending upon licensing and
terrain. The user and/or professional installer is responsible for making the correct calculation for ERP in
other environments.
Industry Canada antenna compliance
Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type
and maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce potential
radio interference to other users, the antenna type and its gain should be so chosen that the equivalent
isotropic radiated power (E.I.R.P.) is not more than that necessary for successful communication.
This radio transmitter, 11169A-XETA4m, has been approved by Industry Canada to operate with the
antenna types listed below with the maximum permissible gain and required antenna impedance for
each antenna type indicated. Antenna types not included in this list, having a gain greater than the
maximum gain indicated for that type, are strictly prohibited for use with this device.
The installer of this radio equipment must ensure that the antenna is located or pointed such that it
does not emit RF field in excess of Health Canada limits for the general population; consult Safety Code
