HDMI over Dual CAT5/CAT6 device set extends your HDMI video and audio signal up to 164 ft. (with CAT6 cable) from the HDTV source. This is a perfect and reliable solution for situations where your HDMI compatible HDTV needs to be located in maybe a separate room or floor from where the HDMI source device is securely located. Running HDMI over just one run of commonly used CAT5E/CAT6 cable results in even more material cost savings, while still providing greater signal distance and installation flexibility. Tested to perform with satellite HDTV receivers and other higher MHz AV devices. Maximum resolution/bandwidth of 165 MHz at 1080P.
