I don't know about European freq issues, but I do the exact same thing with my antennas. I run them forward in a tube, and do a u-turn from the right side to the left side of the fuse. I adjust it so that about 2 inches will come out just under the tail. I tape this to the side of the fuze. Darrol Cady sells some clear tape that works perfect for this. It is very flexible and holds up well to fuel.

Some hardware stores sell the same tape in colors, so you can match your planes. The colors are not quite as flexible, but still work well. They have a very nice shade of Green.
