Do you have a UPS on your amp/preamp? I was just thinking about this today because someone is coming out within a week to move the DB8 up on the roof since the attic has too much signal blocked for reliable channels on 2 of 6 that I want.
Then I got to thinking, If the power goes out, all my electronics except for the antenna are on a ups! So if i'm recording OTA, i'm SOL. I may even have to buy a smaller ups and stick it in the attic...but then again, are they meant for unheated attics? I doubt it. This poses a problem for me now because I dont know how things will be wired after the install.
Therefore, I was going to just have him do a barrel connection where the antenna drops to the ground because in the future I'll be very likely drilling thru my crawlspace (or wire somehow thru my attic) instead of putting the wire around the entire house outside/in breezeway (where no ups is now anyways). But a real pain to do that in winter. (long story)
