This is a very simple 1m long TNC to RP-SMA cable. We like to use this cable to connect our ultra high-frequency RFID antennas to an equally powerful reader board. This cable is perfect for extending pre-existing cables to give yourself a better range of operations when managing your RFID projects.
Each cable is capable of a nominal impedance of 50Ω with a cutoff frequency of 39GHz. If you are looking for a good antenna to pair this cable with, we recommend our UHF RFID Antenna.
Note: If you are looking to use this cable with the UHF RFID Antenna and the Simultaneous RFID Reader, you will also need the RP-SMA to U.FL Interface Cable to connect everything.

Plain-language definitions for the technical terms used above.
- Impedance
- Impedance is the total opposition a component or circuit presents to alternating current, measured in ohms, combining resistance with frequency-dependent reactance. It appears in many contexts, such as matching a speaker's impedance (for example 4 ohm or 8 ohm) to an amplifier or the input and output impedance of signal circuits, and a correct match helps avoid weak signals, distortion or damage.
- SMA
- SMA is a small threaded coaxial (RF) connector widely used to attach antennas and other radio-frequency cables. A device with SMA antenna ports needs antennas or pigtails with matching SMA connectors, or a suitable adapter, to connect to them.
