Replacing the 4 db distribution amplifier with an AP4700 preamp will improve the sensitivity of your system by at least 10 db. This is due to noise figure differences between the AP4700 and a typical TV set. The distribution amplifier didn't have enough gain to override the noise figure of the TV sets, but had too much gain for the stronger VHF stations..
