Update: The FIOS installer somehow messed up the DTV reception throughout the house. I have to go in the attic and see what's been tampered with.
I went up there and saw that the installer COMBINED all the TV outputs from the A-Neutronics amplifier through a Monster Cable -5.7db 3-way splitter. So today's TV recording is trashed, unwatchable. Ah, it's reruns of Hawaii Five-O, Magnum, p.i., and Hogan's Heroes.
I took out and reset my DTV connection to receive the amplified signal without the splitter, like the way it was set before. Still no high VHF, but everything else is back the way it was.
I'll post a sign to not touch my setup up in there.
