Well, I formed it to parrallel antennas, but the range came down to 5 metres... So 1 antenna works for me best i think. damn :/
Do you mean that you made the arms of each antenna parallel to one another? They need to be stretched out opposite to each other, in a straight line.
Then, jremington meant that the receiver antenna must be positioned parallel to the transmitter antenna.
You might have done this, but I thought I'd better clarify....

yea i did exactly that, with poor results. I think there is no way to get a better range..

With that attitude, perhaps you should just give up.

Yes there is a very good way to get better range, but unfortunately it needs right test-equipment.

The cheaper way is a basic knowledge of antenna theory and some experimentation.   Do you have a picture
of the current setup?  The things that will affect performance are mainly nearby metal objects especially any
that about 1/2 wavelength across as they may resonate at the frequency of interest.  In particular the ends of
the antenna need to be poked out into free space, not next to any other conductor, or the whole antenna will
be de-tuned.

Well this is my actual Setup. Just a 17,3 straight wire (cu). I brazed the second antenna out, because it didn't increse the range.
