Missing local Channels

Old Tablo died, got a new one under warranty. New channel scan (repeated a number of times) would not pick up 2 local channels that I could access with the old Roku. Outdoor antenna located in the attic, amplification is off. I have adjusted the antenna a number of times without improving reception. All are broadcasting in VHF. Located in northeast Seattle. Antenna is aimed at the FOX tower which is the most distant. The ABC, NBC, CBS towers are closer are all on the same hill just a bit to the east. The PBS tower is a bit further east but closer. I can’t pick up FOX or PBS.

Any ideas???

My first thought would be to double-check all your antenna connections.

The channels I am receiving come in great. No buffering, clear picture and sound.

The new 4th generation Tablo has an amplifier, turn it off and see if those channels are found

It is off.
