***When placing the radio beacon make sure it is directly under the top platform and as close as you can get to the tower, if you place it where I have mine in the video it may not work***
I found this out launch day of Battlefield 3, I've been using them ever since... Thought I'd share how I get into these spots, without using a jet or heli, thus not ruining the game for other players!
It may mess up if you put the radio beacon in the wrong spot, but you'll just parachute back down to earth...
