I don't want to add to the confusion and to me it's obvious a couple here know electronics (brother did too, RIP N9NGI) I freely admit I am electronics dummy, and any help you can offer is appreciated, a simple drawings easier for me to follow.
On the OTA booster there are 3 connections 1 in 2 out, from there I split again off one leg. The boosters in the bedroom and that TV works great, farthest living area not so good. I have never used the basement factory connection for outside TV. If I under stand I need to get one splitter that will run coax to each TV. One of the posts talks about running RG6 from the antenna to the booster, worth tearing apart to change? This is my 3rd 5W and it's the worst on reception.
