## Summary description

This Rangeful HF400 coaxial cable features RP‑SMA male to RP‑SMA female connectors, a 20 m length, 50 Ω impedance and full copper construction. Designed for RF signal transmission, it suits antennas, routers, ham radio and test equipment requiring RP‑SMA connections. The 20 m run provides flexibility in equipment placement and reliable signal transfer for indoor and sheltered outdoor setups.

## Long description

This Rangeful HF400 coaxial cable provides a 20 m link with RP‑SMA male to RP‑SMA female terminations, 50 Ω impedance and full copper conductors. It is intended for RF signal transmission between devices that use RP‑SMA connectors, offering a long run for flexible placement of antennas, routers, ham radio equipment and test instruments. The HF400 dielectric and shielding design supports consistent signal transfer for indoor and sheltered outdoor installations where a longer cable is required.
Advantages
The full copper center conductor and braid ensure low loss and reliable conductivity across the 20 m length while maintaining 50 Ω characteristic impedance. RP‑SMA male to RP‑SMA female connectors provide compatibility with devices that use reverse‑polarity SMA interfaces. The HF400 cable construction balances flexibility and mechanical durability to make routing and installation easier in limited spaces and along walls or through conduits.
Suitable for
 Connecting external antennas to routers or wireless access points
 Ham radio stations requiring RP‑SMA connections for transceivers or antennas
 Linking test equipment and measurement devices with RP‑SMA interfaces
 Indoor or sheltered outdoor RF installations where a 20 m cable run is needed
Key specifications
 Cable type: HF400 coaxial
 Connector configuration: RP‑SMA male to RP‑SMA female
 Length: 20 m
 Characteristic impedance: 50 Ω
 Conductor material: full copper center and copper braid
 Typical use: RF signal transmission for antennas, routers, radio and test gear
How to use
Attach the RP‑SMA male connector to the RP‑SMA female socket on the transmitting or receiving device, and secure the RP‑SMA female end to the corresponding RP‑SMA male connector on the antenna or accessory. Ensure connectors are hand‑tightened without excessive force to avoid damaging the connector threads or center pin. Route the cable to avoid sharp bends and heavy kinks; maintain a gentle radius at bends to preserve impedance and minimize insertion loss.
Usage recommendations
For best performance, keep the cable run as short as practical and avoid routing near high‑power electrical lines or devices that may cause interference. Use additional weatherproofing at outdoor connection points if the cable is exposed to moisture or temperature extremes, and inspect connectors periodically for corrosion or mechanical wear.
