F Type DC Blocker

The F-Type DC Blocker is an essential in-line coaxial device designed to block DC voltage from passing through an RF signal path. Commonly used in satellite, antenna, MATV, and cable TV installations, it protects sensitive equipment from unwanted voltage, especially in systems where DC power is present for powering LNBs or amplifiers. With F-Type male to F-Type female connectors, the DC blocker installs easily between devices or cable runs without affecting the RF signal. Built with quality shielding and low-loss construction, it ensures clean signal transmission while isolating DC power where needed.
