A friend of mine is having a party on a ranch. Hundreds of acres. There are big power lines going by the house, maybe 200 feet or so. I want to fly around the perimeter and get shots and video. I have heard that cell towers affect your signal. Does anyone have any knowledge about these kinds of lines. Do they cause problems? Is there a recommended distance that one should not fly by these. These lines are from a nuclear power plant. I mean big.
