hi,i am new to the forum,and have been having serious problems with ota reception.I have a outside antenna about 35ft high with a rca preamp install right under the antenna.coax rg6 leads down to a 4way power pass splitter,from there,i have 3 tv sets hooked to splitter going in different directions.On any given day at different times of day television in the living room loses signal,pixalate and just plain horrible to watch.other 2 tvs playing on the same channel showing perfect picture.Some time this television shows nicely no problem.i am always out rotating my antenna to no avail.Now here comes the kicker.There is a cellphone tower about a quarter mile across my back yard.Wow could it be it.If so what could i buy to correct this problem.
