Coaxial cable Rangeful HF240-RPTNCM-SM-20 20 m, SMA Male to RP-TNC Male

The Rangeful HF240-RPTNCM-SM-20 is a 20 m coaxial cable fitted with an SMA male connector at one end and an RP-TNC male connector at the other. It delivers a ready-made RF link for installations that require an extended preassembled lead between equipment and antennas, test instruments or wireless devices. The cable is intended for applications where SMA to RP-TNC interfacing and a consistent, flexible cable run are needed.

Advantages

This coaxial lead simplifies setup by providing a long, continuous connection without the need for adapters or multiple short patch cables. The preterminated SMA male and RP-TNC male connectors ensure straightforward mating with compatible antenna ports and test equipment. The cable construction balances flexibility and mechanical durability, helping to route the cable through conduit, racks or along walls while maintaining signal integrity over the 20 m length.

Suitable for

• Connecting antennas to wireless routers, access points or radios requiring SMA ↔ RP‑TNC mating
• Long-reach RF test setups and laboratory measurements
• Signal distribution in temporary or permanent installations where a single 20 m lead is convenient
• Field equipment connections where quick, tool-free mating is required

Key specifications

• Cable length: 20 meters
• Connector A: SMA male
• Connector B: RP‑TNC male (reverse-polarity TNC male)
• Cable type: coaxial RF cable designed for general-purpose RF use
• Typical uses: antenna connections, RF testing, wireless device interconnects

How to use

Route the cable from the transmitting or receiving device to the antenna or test instrument, avoiding sharp bends and excessive crushing. Align the SMA male with the SMA female port and hand-tighten the SMA coupling nut until snug; avoid over-tightening. At the other end, align the RP‑TNC male with the mating RP‑TNC female and hand-tighten the coupling nut until secure. Verify proper mating and check for stable signal or expected measurement results. When deploying outdoors or in exposed locations, protect connectors and cable from moisture and mechanical strain using appropriate boots, gaskets or conduit.

Usage recommendations

To maintain signal quality and prolong service life, avoid bending the cable below its minimum bend radius, minimize repeated flexing near the connectors, and keep connector interfaces clean and free of debris. For permanent outdoor installations, use additional environmental protection at the connector interfaces and secure the cable along its route to prevent movement.
