I think you must mean -5 to -10 dB Noise Margin (NM) range. Signals that are -5 to -10 dBm are extremely strong; strong enough to overload a tuner.
If an antenna is in the clear, it is possible to receive signals as weak as -15 dB NM. It is not possible to receive signals any weaker than NM -15 dB, because they are below the Thermal Noise Floor at -106 dBm. If you are able to receive signals weaker than -15 dB NM, either the TVFool report is wrong or the signals have been enhanced by Tropospheric Propagation.
Where the -106 dBm comes from:

I expect you to spend at least as much time testing as I have spent answering your questions.
Good luck
