The reviewer found the single biggest reason to buy is the low measured loss at higher VHF\/UHF frequencies, which keeps signal strength and SWR stable over distance. Build quality and a secure connector termination also stand out, making it a practical choice when a durable outdoor-capable cable is required.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eLow loss performance:\u003c\/strong\u003e At 450 MHz the 40ft KMR400 cable shows less than 2.8 dB loss and an SWR around 1.25, helping preserve signal over long runs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRobust conductor design:\u003c\/strong\u003e The inner conductor is copper clad aluminum while the outer uses aluminum foil plus a tinned copper braid to protect the signal over distance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurable jacket and connectors:\u003c\/strong\u003e A high-quality PVC jacket provides water resistance for outdoor use and the nickel-plated connector shells resist oxidation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecure connector termination:\u003c\/strong\u003e Each UHF male connector is sealed with a 2.2 in heat shrink tube bonded with adhesive to reduce the chance of connector pull-out.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVersatile applications:\u003c\/strong\u003e Works with CB and ham radios, SWR meters, antenna analyzers, VHF marine equipment and surge protectors in typical ham and mobile setups.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThis cable is aimed at ham radio operators, CB users and marine VHF owners who need a long, reasonably low loss feedline without stepping up to heavier commercial hardline.
