Key specifications
Cable length: 2.1 m
Connector A: SMA (reverse)
Connector B: TNC (male)

How to use
Ensure both devices are powered off before connecting the cable. Align the SMA (reverse) connector with the corresponding SMA (female) port and carefully screw on until hand-tight, avoiding over-tightening. Align the TNC (male) connector with the TNC (female) port and secure by threading until snug. After connections are secure, power on devices and verify RF link or signal strength according to the device manufacturer's procedures.
Usage recommendations
Avoid sharp bends and excessive pulling on the cable to maintain signal performance. Keep connector threads clean and free of debris; if exposed to outdoor environments, consider additional protection at connector junctions. For best results, use this cable for short- to moderate-length RF connections within the rated operating environment of your devices.
