Connecting the CTM-200
For optimum performance antennas should be mounted in a vertical orientation as high up as possible and with
clear line of sight in all directions. For regulatory purposes it must be mounted in such a position as to maintain
a separation distance from any person of at least 20cm (8”).
4.2.1
Cellular
The cellular connection supports MIMO (multi-in multi-out). For best performance ensure both primary and
secondary cellular antenna connections are made to an antenna that supports diversity or to two separate
antennas. If only one antenna connection is available, use the connection labeled “PRI-RF”.

4.2.2
GPS
The GPS antenna should be an active type of antenna with a gain of at least 26dB and compatible with a 3.3 volt
DC supply provided directly by the CTM-200 via the coax cable. The antenna installation should typically be on
an upper horizontal surface of a vehicle or building with a clear 360-degree view of the sky.
Connect a suitable GPS antenna to the port labeled “GPS”. For best performance select a GPS antenna that
supports GPS/Glonass/Galileo(GNSS) constellations.

Wi-Fi/Bluetooth
Local Wireless via Wi-Fi (802.11bgn) and Bluetooth (802.15.1) requires an external Wi-Fi antenna connected via
a reverse polarity SMA connector

Satellite (Optional)
The Chameleon CTM-200 “Dual Mode” Gateway features an Iridium Subscriber Unit (ISU) satellite module
(SBD9602) and a mini-PCI express/NGFF form factor cellular wireless module. With the internal ISU,
