The slope was about 10 degrees downhill from Northeast to Northwest from an elevation of ~290’ ASL and ~ 6 degrees uphill to the South – the hilltop was about 400’ behind me up another 30’ in elevation. I used about 60  1/4 wavelength radials – 40 of which I had pointing downhill.   It was at the bottom of the sunspot cycle (1987) and I was able to hear and work almost anything in Asia over the pole on 40 and 80 that stations with yagis and 4-squares had trouble hearing.

And that's with 600 ft of RG8X sucking nearly 4 dB on 40M and 2.6 dB on 80!
