This is a 300mm long Male TNC to Male SMA cable. 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 a device located on a monopole or tripod without having too much extra cable. And if you need a longer cable we've got an SMA extension!
Each cable has 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 GNSS Multi-Band L1/L2 Surveying Antenna.
