Re: WISP dish points at ground... It actually is pointing at the horizon.
This is a common visual misconception compared to satellites aimed at the sky.
The radio hits the back of the dish at an angle... Therefore the received signal is also at an angle to the dish, not straight on.
For instance if the radio is offset about 30deg from the back dish, then the received signal is actually 30deg higher than the direction the "dish" is pointing.
Sounds like a decent connection, but if you have any trees in the way they are the reason you lose it in a storm I would imagine. Leaves are a bad thing to begin with, but wet leaves are much worse.
