Constructed to meet or exceed LMR400 specifications, it combines a solid CCA center conductor, braided tinned copper shielding, and weather-resistant jacketing for low VSWR and long service life. It is not intended for TV coax or cellular antenna systems.\u003c\/p\u003e\n\n\u003ch3\u003eHow much signal loss should I expect over 50 feet?\u003c\/h3\u003e\n\u003cp\u003eThe CFD400-style construction dramatically reduces attenuation compared with older RG-8U and RG-213U cables, so you retain more usable signal across the run.
