SpectraPoint 2000 Rooftop Unit (RTU)
Model No. RTU2000-28-3
Product Information Primer
The RTU integrated antenna and radio frequency (RF) transceiver provides wireless transmission and
reception capabilities in the 28-GHz frequency region. Received signals are down converted from the
28 GHz band to the Intermediate Frequency (IF) L-Band and are sent to the NIU. IF signals from the NIU
are up converted and transmitted over-the-air on the 28-GHz band. Model RTU2000-28-3 does not require
a pilot tone.
The RTU consists of an antenna with radome, housing, and electronics including a down-converter/IF strip
and an upconverter/transmitter. RTU polarization is set during installation to match the polarization of the
Base station.
The RTU connects to the Network Interface Unit (NIU) through two cables: the transmit cable and the
receiver/power cable. Refer to the Installation section of the applicable CPE Equipment Manual for more
detailed instructions on the installation of the RTU.
An Installation Worksheet or similar installation order provides site-specific parameters. A sample
Installation Worksheet is provided in Appendix A of the
CPE Equipment Manual
Installation section.
The equipment required to install the NIU is listed in the CPE Installation Tools and Supplies table in the
CPE Equipment Manual
Installation section.
Warning!
The RTU installation and cabling must meet national and local
codes. A properly installed grounding wire must be attached to
the RTU.
