Fabio - the hanging loose method is one of the suggested methods straight from DragonLink. This is documented on their website. Have a look.

For sport flying, and for shorter range electric FPV planes with no landing gear and limited space to mount an antenna, the antenna should be mounted as in the second picture, with the ground side just hanging below the fuselage. This will reduce performance a little bit, but not a whole lot. Unless you fly more than 10 KM away, you will never even notice the performance reduction you get from this free wire hanging in the wind. The wires I use to construct the antenna are very strong and flexible, so this installation will last many years on the tail of an electric plane like this without breaking, even though the wire drags along the ground in landing.
