50 Ohm Leaky Coaxial Cable
50 Ohm Leaky Coaxial Cable is designed for wireless communication systems that require continuous RF signal coverage along tunnels, subways, rail transit, underground corridors, mining areas and other enclosed environments. This series provides stable signal transmission, controlled signal leakage and reliable performance for distributed radio coverage applications.
