XRDS-RF 9ft KMR400 UHF Coax Cable | PL-259 UHF Male | Low-Loss 50 Ohm CB Cable for Ham Radio

Overview

Discover the XRDS-RF 9ft KMR400 UHF coax cable, engineered for steady performance in demanding radio setups. The inner conductor uses copper-clad aluminum with a 0.41 inch diameter, a design choice that supports a larger center conductor and improved signal retention compared with common RG58 or similar coax. Built to balance performance with practical reliability, this cable aims to deliver clearer transmissions and more stable reception across busy bands.

Durability meets outdoor readiness. The solid construction pairs a copper-clad aluminum conductor with a UV-proof RF PVC jacket, designed to withstand outdoor exposure for years. A thoughtful combination of materials helps it stand up to sun, moisture, and temperature changes while remaining flexible enough for field arrangements.

Why this cable stands out

• Ultra-Low Loss: larger center conductor supports better signal retention along the line
• Rugged, outdoor-ready build: UV-proof jacket keeps the jacket resilient in harsh environments
• Secure connectivity: nickel-plated PL-259 UHF connector provides a reliable, weatherproof fit
• Moisture protection: adhesive-lined heat shrink seals the ends for lasting protection
