How do I wire the LL 5402 for 1:1? Fist I tried with winding is series but that gave me double voltage... I also tried parallel but then there was signal loss instead. Does anyone know how to wire this transformer for 1:1. Should I just use one winding?

Here is the data: http://www.lundahl.se/wp-content/uploads/datasheets/5402.pdf

Thanks!

The wiring shown in the application example at the bottom of the datasheet shows 1:1 wiring. Primary coils in parallel, secondary coils in series. That gives a turns ratio of Primary: 2||2=2 Secondary 1+1=2, resultings in a turns ratio of 2:2 or 1:1.
