I'd like to see that! skip off a dummy load. however I do agree with your reasoning. I've went down this road long ago and was reasonably confident in the conclusions I made and done the test with evening time ground waves which I preferred working the most. In no scientific way I came to the conclusion that my best DX antenna wasn't the my best ground wave antenna which I already mentioned here with some replies in disagreement. This subject has always been and always will be. There are so many variables with a mobile installation.
