Thinking out-loud here… how can I go above the close-by obstacles?
I don’t think climbing on top of a 50 meter (150 ft) tree, at my age, will be beneficial for my health. I could pay somebody…
I also know that there are helium balloons capable of supporting antennas and other working apparatus for short amounts of time. But that’s not lasting a very long time.
I was contemplating to tether a drone… with the power cable (like CAT-5E) feeding the Pi+dongle+antenna. It would be some 4 lbs (close to 2kg). No need for batteries, but the cable can be heavy for 200’. For voltage drop reasons it will have to be fed with 9V and regulated up there to 5V. Data connection via WiFi. Anchored in triangle with nylon strings.
Not sure if the neighbors, wife or… FAA will like it though (they have regulations for drones, and for captive balloons, but not for captive drones), or how expensive would be, especially with that lifting capability. And 6 motor drones might be more than I would like to pay.
