MOOKEERF KMR400 Coaxial Cable 100ft – 50 Ohm, Low-Loss RF Cable

Overview

The MOOKEERF KMR400 coaxial cable is engineered to minimize loss over longer runs and supports higher frequency use with stable performance. Across a 100‑foot span at frequencies around 900 MHz, it maintains a favorable loss profile and a tight standing wave ratio, offering a practical option for improved signal transfer without added setup complexity.

What makes it stand out

• Ultra Low Loss: at 900 MHz over 100 ft, loss is typically under 3.6 dB with SWR ≤ 1.15, supporting clearer transmissions.
• Rugged construction: inner copper clad aluminum conductor paired with an outer shield of aluminum foil and aluminum magnesium braid for durable protection across distances.

The internal conductor and shielding are designed to preserve signal integrity, while the weatherproof PVC jacket allows indoor or outdoor use, even in challenging environments. The KMR400 is positioned as a strong alternative to popular high‑performance cables like LMR400 and RG8U, offering a balance of rigidity and flexibility for real‑world setups.

Compatibility and practical use

• Works with 50 Ohm RF systems, including cell signal boosters, WiFi repeaters, CB ham radios, and antenna analyzers.
• Broad connector versatility with adapters and common interfaces (UHF, SMA, BNC, TNC, N, TS9) to fit existing gear.

What’s included and packaging
