Built with a copper‑clad aluminum center conductor and a combined aluminum‑foil plus aluminum‑magnesium braided shield, the cable minimizes signal degradation across longer distances while the PVC jacket resists outdoor exposure. It follows the KMR400\/LMR400 form factor for 50 Ω systems and pairs with common RF connectors.\u003c\/p\u003e\n\n\u003ch3\u003eHow much signal loss should I expect on a 50 ft run?\u003c\/h3\u003e\n\u003cp\u003eAt 900 MHz the MOOKEERF KMR400 50ft cable exhibits very low insertion loss — under 1.8 dB — which keeps most of your transmitted or received energy intact over the run. The cable’s standing wave ratio (SWR) is specified at ≤1.15, indicating good impedance matching for 50 Ω systems and reduced reflected power.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eTypical loss: \u0026lt;1.8 dB at 900 MHz\u003c\/li\u003e\n  \u003cli\u003eSWR: ≤1.15 for minimal reflections\u003c\/li\u003e\n  \u003cli\u003eOptimized for VHF\/UHF and common cellular bands\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat is the cable construction and why does it matter?\u003c\/h3\u003e\n\u003cp\u003eThe center conductor is copper‑clad aluminum (CCA), offering a balance of conductivity and lower weight.

Installers, hobbyists and professionals who need a reliable 50‑foot low‑loss RF feedline will find the MOOKEERF KMR400 suited to antenna installations, signal boosters and test setups. If you require long runs with minimal attenuation across cellular and VHF\/UHF bands, and use common 50 Ω connectors, this cable provides a practical, weather‑resistant solution. For special connector assemblies or custom lengths, pair the cable with quality terminations and proper installation to achieve the best results. MOOKEERF also offers customer support if the product does not meet expectations.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can I use this cable for a cellular signal booster?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes — it’s a 50 Ω KMR400 cable compatible with cellular boosters when terminated with suitable connectors.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Does the cable arrive on the wooden spool shown in photos?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No — the product may ship without the wooden spool pictured; you will receive the 50 ft cable itself.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"MOOKEERF","offers":[{"title":"Default Title","offer_id":48413408067741,"sku":"B0F5MLLQST","price":64.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0766\/9596\/1757\/files\/mookeerf-kmr400-front-packaging.jpg?v=1781263912","url":"https:\/\/nexoltic.com\/products\/mookeerf-kmr400-50ft-low-loss-50%cf%89-coaxial-cable","provider":"Nexoltic","version":"1.0","type":"link"}
