Cable only goes up to about 875mhz. It's probably due to attenuation. Splitting the cable to 2 sets causes a 3db drop, 4 way, 6db drop. Using rg59 instead of rg6 causes lots of attenuation also. Higher frequencies have more cabling attenuation and are probably weaker entering the house to start with. With digital, you can't be sure which channels use which frequencies. If you are not using good rg6 cabling, change that first. Then try the amplifier. Unnecessary amplification could mess up the colors (make reds sparkle) on analog service.
