You can achieve even longer distances at lower refresh rates - up to 4K at 30Hz at up to 100 ft. (30 m).The signal booster works by connecting two HDMI certified cables each up to 22.5 ft. (7 m) in length to either side of the signal booster.Hassle-Free InstallationWith its compact design the HDMI signal amplifier is easy to hide for a discreet installation.
