I have an antenna in the attic and then a diplexer to join the Dish Network to the antenna in the attic and then another diplexer to split the signal back to those two sources. I do not have power in the attic and I know some of the amplifiers send power up the coax to the preamp near the antenna. I think I know the answer but need to confirm. I cannot power the preamp downstream of these diplexers, can I? I understand that there is also power between my dish network receiver and my dish as well.
