Coaxial cable Rangeful HF240 SMA male to RP-TNC male, 1 m

Rangeful HF240 coaxial cable with SMA male to RP-TNC male connectors, 1 m in length, provides a compact and flexible RF connection for short signal runs. The cable is intended for linking devices that use SMA and reverse-polarity TNC ports, enabling reliable transmission of radio-frequency signals between antennas, routers, modems and test instruments. Its construction focuses on maintaining signal integrity in applications where connector compatibility and a low-profile routing are important.

Advantages

This 1 m Rangeful HF240 cable combines a durable outer jacket with a flexible inner core to allow tight bends and neat routing in rack, desktop or field installations. The SMA male and RP-TNC male connectors are assembled for consistent mating and reduced signal loss at the interface. The cable's impedance and shielding are designed to minimise interference for short-distance RF links, and the compact connector pair saves space compared with bulkier cable assemblies.

Suitable for

• Connecting antennas to routers or modems with mismatched connector types (SMA ⇄ RP-TNC)
• Portable RF test setups and measurement equipment
• Wireless device installations where a short, flexible jumper is required
• Lab benches and development kits that require frequent cable reconfiguration

Key specifications

• Cable type: coaxial, HF240 series construction
• Connector A: SMA male
• Connector B: RP-TNC male (reverse polarity)
• Length: 1 metre
• Impedance: 50 ohm characteristic impedance
• Typical use: short-range RF signal transmission
• Flexibility: designed for tight routing and frequent handling

How to use

Identify the SMA and RP-TNC ports on your devices before connecting. Align the SMA male connector with the SMA female port and screw it on hand-tight to ensure secure mating; do not overtighten. Align the RP-TNC male with the corresponding RP-TNC female socket and engage the coupling until the connection is secure. Route the cable to avoid sharp bends and avoid placing tension on the connectors. For test setups, connect the cable only while equipment is powered down when recommended by the device manufacturer.

Usage recommendations

Inspect connectors periodically for debris or damage and keep threads clean to maintain optimal signal transfer. Replace the cable if any signs of connector wear, excessive kinking, or degraded performance appear. For longer runs or higher-frequency applications, consider a cable with lower loss or different construction suited to the specific frequency range.
