Coaxial cable Rangeful RP‑SMA male to RP‑SMA male HF240 50 Ω 0.3 m

Rangeful HF240 coaxial cable with RP‑SMA male to RP‑SMA male connectors is a 0.3 m, 50 Ω interconnect designed for short RF links. It provides a compact, low‑loss connection between devices with RP‑SMA interfaces, intended for antennas, wireless routers, test instruments and RF modules. The cable construction focuses on maintaining impedance and minimizing signal degradation over a short run while allowing easy, reversible mating with RP‑SMA female ports.

Advantages

The HF240 cable offers consistent 50 Ω impedance for matched RF systems, reducing reflections and preserving signal integrity across the 0.3 m length. Its RP‑SMA male to RP‑SMA male terminations enable compatibility with a range of modern wireless devices that use reverse polarity SMA interfaces. The short length yields low insertion loss and a tidy installation footprint, while the cable's flexible jacket and standard connector form factor make it easy to route and connect in confined spaces.

Suitable for

• Connecting antennas to routers and access points with RP‑SMA ports
• Linking wireless modules and development boards during prototyping
• Short RF feedlines for test equipment and measurement setups
• Replacing or extending existing short RP‑SMA jumper connections

Key specifications

• Impedance: 50 Ω
• Connector type: RP‑SMA male to RP‑SMA male
• Cable model: HF240
• Length: 0.3 m
• Broadband RF use suitable for typical Wi‑Fi and other ISM band frequencies (short‑run applications)
• Flexible outer jacket for easy routing in compact installations

How to use

Align each RP‑SMA male connector with the corresponding RP‑SMA female port and screw the connector on until hand‑tight; avoid over‑torquing. Use the cable for short interconnections where a 0.3 m jumper is sufficient, keeping bends gentle to maintain impedance characteristics. For test setups, connect one end to the device under test and the other to measurement equipment or an antenna as required. Inspect connector threads and interface surfaces before connecting to ensure clean contact.

Usage recommendations

For best RF performance, keep the cable run as short and straight as practical, avoid sharp bends and excessive mechanical stress, and store the cable coiled loosely when not in use. When using in critical measurements, verify connector cleanliness and consider using a calibrated reference cable for comparison.
