The 1-1/4"C 1-5/8"C Leaky Feeder Cable is designed for tunnel and mining environments and operates in a frequency range between 5 MHz and 2700 MHz for excellent signal transmission performance. The cable is made of helical corrugated copper tube, which ensures its mechanical strength and durability, and can operate stably for a long time in harsh underground environments. This type of leaky cable is designed with specific slots or holes in its shielding layer so that electromagnetic waves can leak out in a controlled way along the length of the cable, so as to achieve effective transmission of wireless signals. It not only supports a variety of communication standards and services, such as voice and data transmission, but also ensures good coverage and reliable communication quality, especially suitable for those enclosed spaces where traditional wireless systems are difficult to deploy or do not work well, such as long-distance tunnels, deep mines, and other scenarios. In addition, the cable has excellent anti-interference and low-loss characteristics, ensuring safe and efficient communication.
