Installation and configuration
Xeta7 Installation
The XETA7 is a board level radio that is intended to be integrated into a customer
package. As such the antenna placement must be done in a manner that is in
compliance with all local regulations.
All transceivers sold under the FCC ID PEJ-XKJS7 must be installed professionally. This
transceiver is only approved for use when installed in devices produced by Xetawave LLC
or third party OEMs approved by Xetawave LLC.
Antenna Installation
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 Xeta7. 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.
Mechanical Interface:
The XETA7 has four mounting holes located 0.100 inches from the outside edge of the
board as seen below:
