Coaxial cable Rangeful HF240 SMA male to RP-TNC male, 12 m

Rangeful HF240 coaxial cable with SMA male to RP‑TNC male connectors, length 12 meters, is designed to transmit RF signals between devices equipped with SMA and reverse‑polarity TNC ports. The cable provides a longer reach for antenna connections, test equipment and network devices that require low‑loss RF cabling. Flexible construction aids routing in installations where space is limited or bends are necessary.

Advantages

The cable combines an SMA male connector on one end and an RP‑TNC male on the other to enable direct connection between mismatched RF ports without adapters. At 12 m length it reduces the need for additional extension components while keeping a practical balance between reach and signal integrity. Flexibility of the HF240 construction makes it easier to route the cable through conduits or around equipment racks, and the connector pairing supports common antenna and test setups.

Suitable for

• Antenna connections where one device uses SMA and the other uses RP‑TNC
• RF test and measurement setups requiring a 12 m coax run
• Network devices and radio equipment that accept SMA and reverse‑polarity TNC interfaces
• Installations needing a flexible low‑loss cable for longer reach

Key specifications

• Cable type: coaxial HF240
• Connector A: SMA male
• Connector B: RP‑TNC male (reverse‑polarity TNC male)
• Length: 12 m
• Construction: flexible cable for easier routing
• Primary use: RF signal transmission between SMA and RP‑TNC ports

How to use

Ensure both devices are powered off before making connections. Align the SMA male connector with the SMA female port and gently thread the coupling nut until finger‑tight; avoid overtightening to prevent damage to connector threads. Align the RP‑TNC male with the RP‑TNC female port and secure it by turning the coupling nut until finger‑tight. Route the cable to avoid sharp bends and pinch points; maintain a gentle bend radius compatible with flexible coaxial cable to preserve signal performance. After connections are made, power on the devices and verify RF link or test readings as required.

Usage recommendations

Use the cable in environments where connectors are protected from excessive moisture and mechanical strain. For permanent outdoor installations consider additional weatherproofing at connector junctions. If signal loss needs to be minimized for very high frequency applications, verify system performance after installation and consider shorter runs or higher‑grade cable if necessary.
