I've been trying to figure out what would save me from climbing up the antennas and after realizing that the winds come from a bad direction, climbing down again. Everyone who lives around antennas knows that this happens more often that getting actually to jump the object. Usually the ground winds are different from the top and the wheather channel is not accurate enough.

I bought a small canister of helium and and a few bright colored balloons. Now, i just fill up the balloon, let it get up and notice if it's going towards to the wires higher up. This has saved me a lot sweat lately. I hope it this might help you too.
