DC-BLOCK DB-6DFM DB-7/16FM-6

DC-BLOCK DB-6DFM DB-7/16FM-6

This DC block is used to prevent DC and low-frequency current surges from flowing along the inner and outer conductors of the transmission line, while allowing RF signals to flow unobstructed. Mainly used in wireless communication systems with leaky cables in subway or high-speed rail tunnels.
