I took out the preamp today. I had already checked all connections and they looked good. I have replaced some of the coax ends with new ones so that I could put rubber boots over them to protect them from the weathers. So without the preamp I am getting a much more reliable signal. I have about 75-100 ft. of coax between the antenna and the tv with a coupler for grounding and a wall plate coupler. With the preamp I was able to pick up real channels 33 and 17, but without it I cannot get these reliably. The preamp was boosting those channels signals to overcome the loss in my coax but it appears it was also the source of my pixiliaztion issues. 33 and 17 are the same as 35 and 12 respectively so I will not be installing a preamp at this point. If I ever need to split my signal I may get a distribution amp instead of putting up a preamp again, but at this point I am very happy with my signal. Thanks for the suggestions and help.
