Questions about video (and RC) reception while flying in mountains, cliffs, etc.
I've been playing with FPV, working toward polarized antennas and the like. I live at the base of some mountains, and I would love to explore them with FPV. I would have plenty to see within a 5 mile radius.
Let me describe the (hypothetical) scenario:
Say I'm flying the plane away from myself toward a cliff which rises above me 1 mile away. My plane has altitude to pass 15ft above the cliff. As it has been approaching the cliff, I had good video reception and an open Fresnel zone. After it passes over the cliff, suddenly the Fresnel zone is blocked by the ground below the plane.
Here's my question-- does my video signal suddenly drop massively?
Then, as I fly around valleys and rock formations, will be video signal be in jeopardy whenever I lose line-of-sight, or something blocks the Fresnel zone?
Does anyone have firsthand experience with flying FPV in mountains?
