This is a 10 meter (33 ft) long Male TNC to Male SMA cable with injection molded stress-relief boots. This is an excellent cable for connecting one of our RTK development boards to a high quality 'UFO' style GNSS antenna. It's long enough to connect to an antenna on the roof to one of our GNSS receivers. The TNC connector allows the cable to be connected directly to an antenna reducing the number of adapters and thus keep signal degradation to a minimum.
The SYV-50-3 cable has a loss of 52dB per 100m (320ft) or 5.2dB of loss per length of 10m. We specifically chose SYV-50-3 cable over RG58 (46 db per 100m) for its good balance of low loss and high flexibility.
Each cable has a nominal impedance of 50Ω. If you are looking for a good antenna to pair this cable with, we recommend our GNSS Multi-Band L1/L2/L5 Surveying Antenna.

Jargon buster
Plain-language definitions for the technical terms used above.
- GNSS
- GNSS stands for Global Navigation Satellite System, covering positioning systems such as GPS and similar satellite networks. It matters here because high-precision GNSS modules can output lots of serial position data that this product can send wirelessly to a computer or phone.
- RTK
- Real-Time Kinematic positioning is a GNSS technique that uses correction data from a base station to greatly improve location accuracy. It matters if you need centimetre-level positioning for robotics, mapping, surveying, or tracking rather than ordinary metre-level GPS accuracy.
- SMA
- A threaded coaxial connector commonly used for antennas. It matters because you need antennas with matching SMA connectors, or suitable adapters, for the LTE and GNSS antenna ports.
