XRDS -RF 12FT KMR 400 UHF Coax Cable with PL-259 — Low-Loss 50 Ohm Cable for Ham Radios & SWR Meters

Overview

Meet the XRDS -RF 12FT KMR 400 UHF Coax Cable, a purpose-built link between your radio and antenna. Its center conductor is copper-clad aluminum at 0.41 inches in diameter, designed to deliver a robust path for signal travel. The result is a cable that supports longer runs and helps preserve signal strength from transmitter to antenna, without the extra fuss of bulky setups. For hobbyists and field operators alike, this cable offers a dependable balance of stiffness, flexibility, and performance.

Durable by design

The outer jacket is UV-proof and built from RF-grade PVC, engineered for outdoor exposure in harsh environments. This means you can deploy it across fences, rooftops, or marine docks with less concern about weathering, grime, or frequent replacements. A solid, tangible feel accompanies each connection, with a jacket you can handle in sun, wind, or rain.

Secure connections you can trust

The cable uses a PL-259 clamp-style connector, not the quick-release crimp type. The nickel-plated RF UHF connectors provide a reliable, weather-resistant connection that stays tight in outdoor rigs and mobile setups. When you attach the end to a radio or antenna, you’ll notice a confident click and a snug fit that remains steady as conditions change.

End-to-end sealing for reliable performance

A lined heat shrink tube seals the assembly at the connector end, with an adhesive-lined sleeve that extends up to about 2.2 inches. This creates a sealed junction that helps protect the crucial interface from moisture and dust, contributing to long-term durability and consistent signaling across seasons.
