The reviewer found the cable well suited to long runs where minimizing signal loss matters, and appreciated that the construction matches expectations for an LMR400-equivalent product. The review highlights real-world handling, build quality, and where the cable fits into antenna, radio and RF patching projects.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eUltra low loss:\u003c\/strong\u003e The KMR400 construction is designed to keep signal attenuation minimal over long 100ft runs for clearer transmission.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e100ft bulk length:\u003c\/strong\u003e Supplied as a continuous 100ft coil that can be cut to length, which simplifies custom installations and reduces connector count.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCopper clad aluminum conductor:\u003c\/strong\u003e The inner conductor balances conductivity and weight to deliver good performance while keeping costs down.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurable PVC jacket:\u003c\/strong\u003e A flexible, water-resistant outer jacket protects the cable for outdoor or rough use without brittle cracking.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e50 Ohm compatibility:\u003c\/strong\u003e Intended for 50 Ohm systems and fits standard connector types when terminated, including N, SMA, UHF and BNC.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWho It's For\u003c\/h2\u003e\u003cp\u003eThis cable is aimed at ham radio operators, antenna installers, and AV technicians who need a long, low-loss 50 Ohm feed and prefer to terminate their own connectors.
