Keonn RF cable SMA male straight - Rev TNC - 9 feet 2.7 m

RF engineers and technicians deploying RFID readers, wireless access points, or test equipment often face the challenge of finding a durable, low-loss cable that can bridge SMA and RP-TNC interfaces without adapters. The KEONN ADCBSMAMSTRTNCMST9 solves this with a 9-foot (2.7-meter) coaxial assembly terminated with a straight SMA male connector on one end and a straight reverse-polarity TNC male on the other. Built for 50-ohm systems from DC to 6 GHz, it maintains a VSWR below 1.5:1, ensuring minimal signal reflection and consistent performance across RFID, Wi-Fi, and general RF applications.

Key specifications

• Connector 1: SMA male, straight
• Connector 2: RP-TNC male, straight
• Length: 9 ft (2.7 m)
• Impedance: 50 Ohm
• Frequency range: DC to 6 GHz
• VSWR: < 1.5:1 typical
• Jacket material: PVC, black
• Conductor: Copper, braided shielding

Why choose it

This cable eliminates the need for separate adapters, reducing insertion loss and potential failure points. The braided copper shielding and PE dielectric provide reliable signal integrity in electrically noisy environments, while the PVC jacket offers flexibility and resistance to everyday wear. The 9-foot length gives you freedom to position antennas or devices without excess slack.

Ideal use cases

• Connecting RFID readers to RP-TNC antennas
• Linking Wi-Fi access points with SMA ports to external RP-TNC antennas
• Test and measurement setups requiring SMA-to-RP-TNC connectivity
• General wireless communication links in the 2.4 GHz and 5 GHz bands

Good to know

The reverse-polarity TNC connector is commonly used in wireless networking equipment to comply with FCC regulations, while the SMA male is standard on many RFID readers and RF modules. Always verify connector gender and polarity before ordering. This cable is not intended for outdoor permanent installation unless protected from moisture and UV exposure.
