This is a basic SMA (Sub-Miniature A) male to female connector cable. Each cable is 1M (39.3in.) long with RG174 housing. The SMA connectors at each end are small enough for most consumer GPS, cellular, and other RF applications and they use a threaded housing to create strong mechanical connections.
These work well for mounting an antenna to the outside of an enclosure, while keeping the electronics neatly inside.

Plain-language definitions for the technical terms used above.
- GPS
- The US satellite navigation system used by GNSS receivers to calculate position and time. Support for GPS is important because it is widely available and often used together with other constellations for more reliable positioning.
- RF
- RF means radio frequency, referring to signals used for wireless communication and other high-frequency electronics. A low-noise, stable power supply is important for RF circuits because power noise can affect signal quality and measurements.
- 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.
