Re: TV- distorted HD images
My first test would be to bypass the splitter. Split 8 ways, you are reducing the signal by 14.7 dB. Since decibels (dB) are on a logarithmic scale, the signal after the splitter is about 1/30th (or about 3.4%) as strong as before the splitter. This is true whether you have one thing plugged into the splitter or eight things plugged in. (Trust me on the math on this one.)
Also, make sure every coax connection is tight.
