The bottom line: it is a workhorse cable for extending antennas and connecting amplifiers where minimizing signal attenuation matters. The cable's ultra low loss construction and an SWR under 1.15 make it a practical choice for installers and hobbyists who want reliable performance over a 35 ft run without complex matching or repeaters.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eUltra low loss construction:\u003c\/strong\u003e The aluminum foil and tinned copper braid shields keep signal attenuation very low so long runs retain usable signal levels.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLow SWR performance:\u003c\/strong\u003e With SWR less than 1.15 the cable supports uninterrupted transfer and reduces reflections at higher frequencies.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasured loss at 1800 MHz:\u003c\/strong\u003e Around 2.05 dB loss at 1800 MHz gives a clear expectation for real-world mobile and LTE band runs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurable outer jacket:\u003c\/strong\u003e The waterproof PVC jacket and clamped connector ends withstand abrasion and outdoor exposure for longer service life.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProfessional connector assembly:\u003c\/strong\u003e The 2.2 in heat shrink with adhesive and clamped design provides a secure, low-resistance connection that resists separation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWide compatibility:\u003c\/strong\u003e This 50 ohm N male to N male assembly is suitable for antennas, boosters, amplifiers and many outdoor receivers.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThe KMR400 35ft N cable is best for installers, amateur radio operators, and anyone extending outdoor antennas where a long, low-loss run is needed.
