Some people apparently have noticed a lot of difference.

However, in this thread the person who noticed the most
difference, also had the tallest & widest trees...

I imagine a wider tree not only captures more radiation,
it also has a lower resistance to ground.

Likewise, a smaller tree will probably have a higher
resistance to ground, while radiation of even shorter
wavelengths will go around it easily.

I do not know if my thoughts correspond to reality, but
this thread seems to have caught enough people's attention
that we may be able to figure this out together...
