## Summary description

Shielded coaxial cable Rangeful HF400 with RP‑SMA male connectors on both ends, 50 ohm impedance and 3 m length. Designed for RF and antenna connections, test equipment, routers and wireless devices that use RP‑SMA interfaces. Provides a reliable low‑loss link for signal transmission and flexible installation in home, lab or field applications.

## Long description

Rangeful HF400 shielded coaxial cable with RP‑SMA male connectors at both ends is a 50 Ω, 3 m assembly built for radio frequency signal transmission. The cable provides a flexible connection between devices with RP‑SMA interfaces, suitable for antenna links, test equipment, routers and wireless modules. Its construction minimizes signal loss and external interference while allowing straightforward routing in home, laboratory or field environments.
Advantages
The cable combines a standard 50 Ω impedance with RP‑SMA male terminations on both ends, offering compatibility with a wide range of RF devices that require reversed‑polarity SMA connectors. The HF400 dielectric and shielding reduce attenuation over the 3 m length and protect the signal from electromagnetic interference. The flexible outer jacket and robust connector housings support repeated installations and moderate mechanical handling without compromising electrical performance.
Suitable for
Connecting external antennas to routers, modems or gateways with RP‑SMA ports
Linking RF test equipment and measurement devices in lab setups
Connecting wireless modules, access points and IoT gateways using RP‑SMA
Temporary field installations and portable diagnostic rigs
Key specifications
Impedance: 50 ohm
Cable type: HF400 (shielded coaxial)
Connector type: RP‑SMA male on both ends
Length: 3 m
Typical use: RF and antenna connections, low‑loss signal transmission
Outer jacket: flexible for routing and installation
How to use
Install the cable by firmly hand‑tightening each RP‑SMA male connector to the corresponding RP‑SMA female port on devices, ensuring correct alignment to avoid cross‑threading. Route the cable to avoid sharp bends and pinch points; maintain gentle bend radii consistent with flexible coaxial cable practices. For lab measurements, allow connectors to seat fully before taking readings; for field use, inspect connector threads and jacket integrity before and after deployment.
Usage recommendations
Use the cable in environments within normal indoor or sheltered outdoor conditions; avoid prolonged exposure to direct sunlight, moisture, or chemicals that can degrade the jacket. When connecting and disconnecting, hold the connector body rather than pulling the cable to extend service life. Verify connector compatibility with your equipment’s RP‑SMA interface and keep spare connectors or short adapters available if you need to adapt to different connector polarities or genders.
