Coaxial cable Rangeful HF400-SM-PL-30 — SMA male to PL259 UHF, 30 m, HF400, 50 Ω, full copper

Rangeful HF400-SM-PL-30 is a 30-meter coaxial cable designed for 50 Ω RF applications, featuring an SMA male connector on one end and a PL259 (UHF) connector on the other. The cable uses HF400 construction with full-copper conductors to provide stable signal transmission and reduced loss over long runs. It is intended for use with amateur radio, CB, antenna hookups and various test setups where a reliable 50 Ω connection is required.

Advantages

The HF400 specification and full-copper conductors offer consistent electrical conductivity and lower attenuation compared with lower-grade materials. The combination of SMA male and PL259 UHF connectors enables compatibility between devices with these common RF ports, while the 30 m length covers extended installations without intermediate connectors. The cable is built for mechanical flexibility and secure threaded connections to maintain signal integrity in typical field and station environments.

Suitable for

• Amateur (ham) radio transceivers and external antennas
• CB radio systems requiring a 50 Ω feedline
• Antenna installations and temporary outdoor hookups
• Laboratory and field test setups where SMA-to-PL259 conversion is needed

Key specifications

• Cable length: 30 m
• Characteristic impedance: 50 Ω
• Cable type: HF400
• Center conductor material: full copper
• Connector A: SMA male
• Connector B: PL259 (UHF)
• Intended use: RF signal transmission with low loss over long runs

How to use

Connect the SMA male end to equipment with an SMA female port and the PL259 end to devices or antennas with a UHF mating connector. Ensure both connectors are clean and free of debris before mating, and tighten threaded interfaces by hand until secure; avoid overtightening to prevent damage to connector threads. Route the cable to minimize sharp bends and kinks, support long runs with appropriate clips or ties, and keep the cable away from sources of electrical noise where possible.

Usage recommendations

For best performance, verify that connected equipment expects a 50 Ω feedline and use proper grounding for outdoor antenna installations. Inspect connectors periodically for corrosion or wear, and replace the cable if the center conductor or shielding shows visible damage. When running the cable outdoors, protect connector ends from moisture with suitable sealing or weatherproofing caps.
