Low picture quality using Philips HDMI cable

Implementing a passive signal 4-way splitter will technically attenuate the signal. This might affect the picture quality negatively when: * The source (antenna) signal is too low * You are using long runs of coaxial cable Solution: Install an RF signal amplifier in front of the signal splitter, preferably close to the source. This will ensure the fixed attenuation of the splitter (-7.4 dB) has no effect on the signal quality of the outputs. Note: the attenuation does not depend on whether there is 1, 2, 3, or 4 outputs connected.
