Overview

Meet the XRDS-RF 18FT KMR 400 UHF coaxial cable, built to support reliable radio links in demanding environments. With a 50 ohm impedance and a generous 18-foot length, this cable is designed to strike a balance between signal integrity and practical reach for portable and outdoor setups.

Key design choices focus on maintaining strong signal quality while standing up to real-world use. The inner conductor is copper-clad aluminium, providing a robust core that helps preserve signal as it travels from your transceiver to the antenna. A larger center conductor translates to better retention of the original signal compared with some lighter-duty options, especially across longer runs.

Why XRDS-RF KMR 400 Stands Out

  • Ultra-Low Loss— The copper-clad aluminium core supports effective signal retention, helping your radio links feel more consistent across distances.
  • Durable, Outdoor-Ready Build— A flexible UV-proof RF-PVC jacket is designed for long outdoor exposure, keeping up with harsh weather and sun exposure.
  • Secure PL-259 Clamp Connectors— Nickel-plated, waterproof UHF connectors deliver a dependable connection even in challenging conditions, reducing the risk of accidental disconnections.
  • Sealed Terminations— An adhesive-lined heat-shrink tube extends to the connector, creating sealed ends for weather resistance and long-term integrity.
  • Versatile Applications— Ideal for CB radios, ham radios, SWR meters, VHF/HF setups, antennas, marine installations, walkie-talkies, tuners, and more.

Real-World Scenarios

  • Field deployments for portable ham stations where reliable links are essential.
  • Outdoor antenna runs on boats or in coastal environments where weather resistance helps with durability.
  • Stable connections in CB radio setups where long runs are needed between the radio and the antenna.
  • Testing and tuning with SWR meters or antenna analyzers to optimize performance.

Installation Tips

  • Use the PL-259 clamp connector for a secure fit to compatible UHF antennas.
  • Take advantage of the heat-shrink end seal to protect exposed terminations from moisture.
  • Ensure the 50 ohm impedance matches your radio system for best compatibility.
