Sylvain Munaut e80c6d1961 design: Make the traces 40 mil wide with 12 mil GND separaton 
This should keep a ~ 55 ohm impedance (close enough)

Sylvain Munaut ab37213276 design: Move the outside holes closer to their optimal position 
According to the WAG100 datasheet they should be 36.25 mm from the center
axis. Now they are 36.2 mm from the center axis which should work fine.
