The formula used to calculate signal strength in TVfool does not use ground reflections to figure signal strength. Yet ground reflections can add up to 6 db to the signal strength.
Read the paragraph "Average Power Diagram for UHF" in the following web site:

In your case, the signal enhancement near the ground is even more pronounced than the picture shows. I'd assume that the TVfool calculation of a stronger signal at ground level is a coincidence.
Consider an old umbrella stand for your mounting pole. Others use concrete in a 5 gallon plastic pail.
