Built with nickel-plated RF Industries waterproof UHF connectors and an adhesive-lined heat-shrink sleeve, the assembly emphasizes stable connections, low attenuation and long-term exposure resistance without complicated installation steps.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this cable reduce signal loss compared to standard coax?\u003c\/h3\u003e\n\u003cp\u003eThe KMR400 construction targets lower attenuation with a dense braid and optimized dielectric to keep RF energy where it belongs. XRDS -RF measures VSWR under 1.35 across typical VHF\/UHF ranges and reports very low loss for short reference lengths, which scales advantageously over longer runs.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e50 ohm impedance tailored for CB, HAM and analyzer use\u003c\/li\u003e\n  \u003cli\u003eHigh-density tinned copper braid for improved shielding\u003c\/li\u003e\n  \u003cli\u003eReference attenuation: low measured dB at midband frequencies\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat connector and sealing features prevent failure outdoors?\u003c\/h3\u003e\n\u003cp\u003eThe cable uses nickel-plated RF Industries PL-259 male connectors with a heavy mount-clamp installation rather than a crimp-sleeve, reducing the risk of the connector pulling off.
