A direct current (DC) block is a frequency filtering device used in coaxial antenna systems. The DC block allows the passage of radio frequency (RF) signals while blocking audio and DC frequency interference that can damage the system. DC blocks are used in three different forms, known as inner, outer, or inner/outer. These components are further classified by connector type, voltage, and maximum frequency.

The DC block functions by using a blocking capacitor to capture the flow of low-level DC currents through a coaxial cable. It does this while allowing the higher frequency AC currents used in radio signal transmission to pass through in a process called coupling. The DC block can produce limitations on the transmission of all lower level frequencies, including AC frequencies, so modification of the system is sometimes required. This process of modification is called tuning the circuit.

These devices make use of a capacitor to filter out unwanted frequencies that could damage sensitive electrical components of laboratory testing equipment or radio transmitters and receivers. The larger capacitors offer a lower cutoff frequency while smaller capacitors cut off the transmission in a higher range. Where the various DC blocks differ is their placement in the coaxial system.
