MOOKEERF KMR400 Coax Cable 150ft - PL259 Male-to-Male, Low-Loss UHF 50 Ohm

Overview

The MOOKEERF KMR400 150ft coax cable is designed for reliable long-distance high-frequency connections. Its low-loss performance helps maintain signal quality across longer runs, while a robust build supports outdoor and all-weather use. With dual PL259 ends, this UHF jumper is ready for a range of radio setups without compromising compatibility.

Why this cable stands out

At a typical 450 MHz signal frequency, the loss stays below 4.1 dB and the standing wave ratio (SWR) is ≤ 1.25, offering steady performance for enthusiasts and professionals alike. The design emphasizes durability and signal integrity from end to end.

• Low loss over long runs: practical for distance without substantial signal degradation.
• Strong, weather-ready construction: PVC jacket resists moisture; copper-nickel plated shell adds corrosion resistance.
• Signal protection at the ends: 2.2" heat shrink with adhesive creates a bonded, moisture-sealed connection.
• Robust internal build: copper-clad aluminium core with aluminum foil and tinned copper braid helps preserve signal over distance.
• Secure and versatile: clamp-style connector helps prevent breakage; suitable for a variety of radios and meters.

Construction details

The inner conductor uses copper-clad aluminium for a balance of conductivity and flexibility. The outer conductor relies on aluminum foil paired with tinned copper braid to guard the signal as it travels. The outer jacket is a tough PVC layer, designed to withstand outdoor conditions, while a copper-nickel plated connector shell provides added corrosion resistance. The included adhesive-lined heat shrink and clamp-style ends are engineered to stay integrated during real-world use.

Practical uses

This cable is well suited for CB and HAM radio setups, HF amateur radio links, marine VHF communications, antenna connections, SWR meters, surge protection arrangements, and portable Walkie Talkies. It offers a flexible option for both fixed stations and field deployments.

Usage tips

• Plan gentle bends and avoid sharp turns to protect the integrity of the inner conductor.
• Keep the cable away from high-power lines and sources of EMI when possible.
• Secure connectors to minimize movement and reduce wear over time.
