Ard,
Yes, this is a very good idea - however, you need to consider how many
_statistically_significant_ points you need too get a proper antenna
pattern - and you need to be aware that you can get spurious results
from reflections - so ideally you will do the same exercise from
several points to try to eliminate the effect of these spurii.
The technique is a form of 'tomography', used not only by antenna
engineers when needed but greatly used by remote sensing scientists and
medical imaging people.
Cheers
Ian

Just came up with an idea; if you war drive your neighbourhood -and
beyond- with GPS enabled, save the map, put up a dish-setup and swipe
it across the neighbourhood, you can determine the reach of the dish
setup.
From the map simply calculate the distance of an AP found in the war
drive to your dish setup .
Even without hi tech equipment it is then easy to find out what setup
works the best for you.
