Yesterday I took a short trip to the highest point on the island I live on and grew up on. There is a water tower there and we would climb to the top when we were kids. The view in all directions was awesome. Although I am to old to climb it today I took the drone to get some shots. Much to my disappointment when I arrived I found the site was an antenna farm, five or six cell towers that looked like every type of antenna imaginable were mounted on them. I decided not to fly and risk my drone. My question is would it be safe to fly by these antenna towers if so how far from them would be safe? Thanks in advance to any one knowledgeable enough to this question.
