Those readings are lower than they should be with a preamp; too many in the very weak category. How do the readings compare with the two meters using signals that are strong enough for the Minimax-M?
Those readings do match the ones in post #11 allowing for the gain of the 3412.
Is this the test setup?
Ant > preamp > coax > grounding block > power inserter > meter
Those readings are dBmV, right?
A reading of -32 dBmV is equal to -81 dBm. Tuners drop out about -85 dBm. That's too close to dropout.

The DB readings were NOT steady and changed 2,3,4 DB per reading?

That's normal; OTA signals are constantly changing in strength.
After looking at your tvfool report, something is still wrong. Unless something is blocking the signals on the way to the antenna, you have a problem with the antenna, preamp, coax downlead, or grounding block.

unless the report is wrong.
