LMR-300 High-Performance Low-Loss Flexible Coaxial Cable
LMR-300 coaxial cable represents an ideal balance of low attenuation and physical flexibility within the renowned LMR family. With a nominal diameter of approximately 0.300 inches, it offers significantly better signal preservation than smaller cables (like LMR-195 or RG-58) while remaining far more flexible and easier to handle than the larger LMR-400. It is the perfect choice for medium-length antenna runs, WISP installations, and mobile communications where both efficiency and practical routing are critical.
