LA-112 RG-58 50 Ohm Coaxial Cable is best used when more distance is needed for the antennas to have better coverage. Measured at 500 ft. Recommended for coaxial runs less than 100 ft. (30.5 m) at 72 MHz or 50 ft. (15.24 m) at 216 MHz. Signal loss for 72 MHz is 2 dB per 50 ft. Signal loss for 216 MHz is 4 dB per 50 ft.
