In this plot I included the 40, 50 and 60 dBuV contours that were mentioned in another post. 

As before:

1 watt to the antenna.

Antenna center is 30 feet abover ground level.

0 dBi 🙂

The area around here is hilly so you get an idea of the effect terrain has.

What height above ground was used for the fields shown in that plot, at those receive locations?

Then you used 30 feet for the height of the radiation center of the transmit antenna, AND 30 feet above the earth at all those receive locations to calculate the field intensities/contours shown on your plot?

I misread your question sorry.  The RX antenna height was 1 meter.
