• [9]: GNSS input #1. A TNC coaxial female connector
allowing you to connect the first GNSS antenna to the
receiver via a coaxial cable.
• [10]: GNSS input #2. A TNC coaxial female connector
allowing you to connect the second GNSS antenna to the
receiver via a coaxial cable.
• [11]: External GSM antenna (optional). A coaxial female
connector (SMA type) allowing you to connect an external
cellular antenna.
The SP90m having a built-in GSM antenna, no external
GSM antenna is usually required. In case of adverse
reception conditions however (e.g. SP90m mounted in a
rack), an external antenna can advantageously be used for
better reception. Run the Web Server (Receiver> Network>
Modem> Modem Antenna) to choose which of the internal or
external antenna should be used.
The SP90m uses a GSM antenna when it sends or receives
RTK or differential corrections via its GSM modem.
• [12]: UHF radio connector. A TNC coaxial female
connector allowing you to connect a radio whip antenna.
This connector is available only if the SP90m has been
fitted with a radio module.
Warning! Do not confuse this coaxial input with the GNSS
inputs. Connecting a GNSS antenna to the UHF input
might damage it if the embedded UHF transmitter is used
