It’s engineered to reduce insertion loss and keep a reliable, sealed connection between transceiver, SWR meter, antenna tuner, or antenna feed point. The cable’s thicker conductor and adhesive-lined heat-shrink sleeve aim to improve signal retention and outdoor durability compared with thinner RG-58 style jumpers.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this cable reduce signal loss on short runs?\u003c\/h3\u003e\n\u003cp\u003eBecause KMR400-style coaxuses a larger center conductor and heavier dielectric than RG-58, it has lower attenuation over the same length. For two-foot jumper runs, that means less signal degradation and more consistent SWR readings in the receive and transmit path. The nickel-plated UHF connector also minimizes contact resistance at the mating surface.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eThicker copper-clad aluminum center conductor for improved conductivity\u003c\/li\u003e\n  \u003cli\u003e50 ohm impedance suited to most CB, ham and VHF\/UHF equipment\u003c\/li\u003e\n  \u003cli\u003eLow-loss construction reduces power dissipation on short links\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat makes the PL-259 connector on this cable reliable outdoors?\u003c\/h3\u003e\n\u003cp\u003eThe PL-259 supplied is nickel-plated and designed for secure threading onto SO-239 sockets. An adhesive-lined heat-shrink tube is included to seal the braid and connector joint after assembly, which helps keep moisture and corrosion out of the critical contact area. The jacket and connector plating together support long-term outdoor exposure without premature degradation.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eNickel-plated UHF (PL-259) male for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eAdhesive-lined heat-shrink sleeve provides a water-resistant seal\u003c\/li\u003e\n  \u003cli\u003eUV-proof RF-PVC outer jacket rated for extended outdoor exposure\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhich devices and setups is this cable compatible with?\u003c\/h3\u003e\n\u003cp\u003eThis 2 ft, 50 ohm cable functions as a jumper between common amateur and commercial radio components. Use it to connect CB radios, ham transceivers, SWR meters, antenna tuners, or portable analyzers.
