Leaky Coaxial Cables

Leaky coaxial cable, also known as radiating cable (leaky feeder), features regularly spaced slots on its outer conductor, allowing it to radiate electromagnetic waves uniformly while transmitting RF signals and to receive external signals at the same time. It is mostly 50 Ω impedance with a wear-resistant, waterproof outer jacket, and offers good shielding and signal radiation performance. It is commonly used in signal-blocked areas such as tunnels, subways and underground parking garages to fill the coverage blind spots of ordinary antennas. Simple to install, it can be laid continuously along a passage to provide seamless wireless coverage, and is often used with base stations, two-way radios and rail transit communication systems to reliably guarantee wireless communication in long, narrow enclosed spaces.
