Hmm, strange. It is definitely helping in my situation? Without the in-line amplifer, I run a scan and cannot pickup ABC, doesn't even detect or add as an available channel at all. This is the same on 3 different TV's. With the amplifer it picks up ABC, adds as an available channel and comes in nicely for a little while. Also CBS is 86-87% without the amp and 91-92% solid with the amp, as well as some other channels that were in the 90's are coming in at 100% now. So what does it mean if it without doubt is helping pickup and strengthening signals?
