Thx ADT.
I plan on going up to the attic later today and removing the pre-amp from the path and connecting the main lead directly to the DB4E. I'll report back.
Question: does the fact that I actually gain signal (on UHF) when I take power away from the pre-amp indicate that it is hurting rather than helping when powered (overload)? Or could that be more a side effect of a faulty pre-amp if that turns out to be the case?
Dist. Amp is this:

On a side note, if I pull power from the dist. amp, I lose signal altogether. I don't know if this by design or if it indicates that the power is really helping that much. Does that amp require power to operate (no passive operation)?
