Abstract

PURPOSE:To reduce the variation in the electric field level of fire fighting radio, by constituting the LCX (Leakage coaxial cable) line for train with the LCX having a constant coupling loss or approximately constant coupling loss and by combinating a radio frequency system different from train radio.
