Designed as a practical equivalent to LMR400\/RG8U, it balances low insertion loss with durable outdoor protection, making it suitable for ham radio stations, CB rigs, VHF marine systems, SWR meters and antenna analyzers.\u003c\/p\u003e\n\n\u003ch3\u003eHow much signal loss should I expect over 35 feet?\u003c\/h3\u003e\n\u003cp\u003eThe MOOKEERF KMR400 35ft cable is engineered to minimize attenuation so your RF system keeps performance across VHF\/UHF bands. At around 450 MHz the insertion loss stays low (under approximately 1.11 dB), and the cable maintains a stable SWR when properly installed.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eMeasured loss under 1.11 dB at ~450 MHz.\u003c\/li\u003e\n  \u003cli\u003eSWR typically ≤ 1.25 when connectors and antenna are matched.\u003c\/li\u003e\n  \u003cli\u003eComparable performance to LMR400 and RG8U at the same length.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eAre the PL259 connectors durable for outdoor or mobile use?\u003c\/h3\u003e\n\u003cp\u003eYes — each end uses a nickel-plated PL259 connector secured with a clamp-style fitting and extended heat-shrink with adhesive for a sealed transition. The longer 2.2\" shrink sleeve and solder-clamp integration reduce the chance of moisture ingress or mechanical separation during handling.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eClamp-style PL259 for strong mechanical bond.\u003c\/li\u003e\n  \u003cli\u003e2.2-inch adhesive-lined heat-shrink for moisture protection.\u003c\/li\u003e\n  \u003cli\u003eNickel-plated shell resists corrosion in marine or outdoor settings.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat construction features make this cable \"low loss\" and reliable?\u003c\/h3\u003e\n\u003cp\u003eThe cable's electrical and physical build work together: a copper-clad aluminum center conductor lowers weight while preserving conductivity; a double-layer shield (foil plus tinned braid) boosts shielding effectiveness; and a thick PVC jacket resists weathering.
