FCC-Approved Antennas (900 MHz)
Fixed Base Station and Mobile
Applications
Horner Modems are pre-FCC approved for use in fixed base station and mobile applications.
When the antenna is mounted at least 20 cm (8”) from nearby persons, the application is
considered a mobile application.
Portable
Applications
and
SAR
Testing
When the antenna is mounted closer than 20 cm to nearby persons, then the application is
considered “portable” and requires an additional test be performed on the final product. This test
is called the Specific Absorption Rate (SAR) testing and measures the emissions from the modem
and how they affect the person.
RF Exposure
(This statement must be included as a CAUTION statement in OEM product manuals.)
WARNING:
This equipment is approved only for mobile and base station transmitting devices.
Antenna(s) used for this transmitter must be installed to provide a separation
distance of at least 30 cm from all persons and must not be co-located or
operating in conjunction with any other antenna or transmitter.
NOTE: The separation distance indicated in the above is 30 cm, but any distance greater than or
equal to 23 cm can be used (per MPE evaluation).
To fulfill FCC Certification requirements:
1. Integrator must ensure required text [Figure A.1] is clearly placed on the outside of the final
product.
2. RS-232/485 Modem may be used only with Approved Antennas that have been tested with
this modem. [Refer to Tables A.1 – A.7]
