The length of the antenna cable may affect the signal strength. Choose the appropriate cable type and length. The
table below can help pre-determine the loss to expect.
GPS Antenna
The GPS chipset used in this device supports a 50 ohm active GPS antenna and is capable of GPS and Glonass sig-
nal reception. Ascertain that the GPS antenna cabling uses an SMA-M type connector. For optimal results, the GPS
antenna should be located so that is has clear and unobstructed access to the sky.
Installation and Verification
When installing the antenna, follow the FCC and Industry Canada guidelines and keep the following in mind:
• Mount the antenna(s) at least 30 cm (12 inches) from other antennas
• Do not install the antenna in a closed metallic enclosure (such as a cabinet or the trunk of a car).
Once a RTU has a signal, the Signal LED indicator will start flashing according to the signal strength. Additionally,
the Web Interface can display the received signal strength (RSSI) on the status page. The unit should have at the
very least one bar of signal strength.
