I though maybe my house had an extra splitter for some reason after the main one so I bypassed the line and put the power supply in attic with a long extension cord and that didn’t help.
I may get another one and see if it makes a difference if either the preamp is bad or the dc adapter is . I am curious if I am over amping the signal bc my strength is really good and I scan about 52 channels without splitter before the summer kicks in.
16db gain for a already good signal might be a lot? Which I did try with splitter to drop it but dunno
Glad it works for you seems like a nice amp.
