Built with a tinned-copper braid and aluminum foil shield, a waterproof PVC jacket, and clamped N-male connectors, it balances low insertion loss, low SWR, and rugged outdoor durability. The cable is engineered for 50-ohm systems including antenna extensions, signal boosters, and high-frequency wireless equipment.\u003c\/p\u003e\n\n\u003ch3\u003eHow much signal loss should I expect over 25 feet at cellular frequencies?\u003c\/h3\u003e\n\n\u003cp\u003eThe KMR400 construction minimizes attenuation so your signal stays stronger across the run. Measured loss at 1800 MHz is about 1.52 dB, which is noticeably lower than common thin coax options. That keeps more of the original RF energy reaching the device and reduces wasted transmit power.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eMeasured loss: ~1.52 dB at 1800 MHz\u003c\/li\u003e\n  \u003cli\u003eDesigned for high-frequency use with low insertion loss\u003c\/li\u003e\n  \u003cli\u003e50-ohm characteristic impedance for compatibility with consumer and pro gear\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill the connectors and jacket survive outdoor exposure?\u003c\/h3\u003e\n\n\u003cp\u003eThe cable uses heat-shrink tubing with inner adhesive at the connector joint and a clamped design to resist separation and moisture ingress. The outer PVC jacket is waterproof and abrasion-resistant, suitable for rooftop, mast, or exterior wall runs. These features reduce the chance of corrosion and mechanical failure in demanding environments.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eWaterproof PVC outer jacket for outdoor use\u003c\/li\u003e\n  \u003cli\u003e2.2\" heat-shrink tube with adhesive at connector junction\u003c\/li\u003e\n  \u003cli\u003eClamped connector design for mechanical robustness\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eIs this cable compatible with my antenna, booster, or router?\u003c\/h3\u003e\n\n\u003cp\u003eYes — the MOOKEERF KMR400 is N male to N male and built to a 50-ohm standard, making it compatible with a wide range of RF devices. It suits antennas, 4G\/ LTE boosters, GMRS repeaters, amplifiers, and test equipment that accept N connectors or can adapt to them.

You trade a bit more weight and diameter for far better RF performance and durability. That makes it a better long-term choice where signal strength and reliability matter.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eSuperior shielding: aluminum foil plus heavy tinned-copper braid\u003c\/li\u003e\n  \u003cli\u003eLower SWR (≤1.15) and reduced insertion loss versus thin coax\u003c\/li\u003e\n  \u003cli\u003eRobust connectors and jacket suited to repeated installation and outdoor use\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for? Installers, hobbyists, and professionals who need a dependable 25-foot 50Ω N-to-N cable for antennas, boosters, routers, or measurement gear will appreciate the MOOKEERF KMR400. It fits use cases where conserving RF power and maintaining signal integrity across longer runs is important — rooftop and mast installations, external antenna feeds, and repeater or amplifier connections all benefit.
