I would say, jump on your roof again and take some hi-resolution photos and post them here so we can have a look.
The whole AC thing is not an issue, the kit that @Gordon808 is will to swap for is more then fine for what we wish to do.
We can always try a test kit scan for piece of mind, but those photo's i'v mentioned above can tell us all we need to know hopefully.
So i would say next step is to take some photos for us. all the way around you.
Just a question, How high would you plan on going? Like length of pole.
For instance i am surrounded by tree's yet because i use a 6m pole i can see over them.
