WFSB is very strong at 76.9 NM(dB) and 3 more channels after WFSB are Very Strong . WSAH is very weak at 4.8 NM(dB). My concern is the first 4 channels being so strong will over load a preamplifier that is used to increase the signal strength of WSAH so I do not recommend a preamplifier. I recommend try receiving WASH on two Tv's with a 2 way splitter , If the WASH signal is too weak with a 2 way split , then install a Channel Master CM3412 distribution amplifier.
