We drove from Mackel along the A14 towards Lille. South of Kortrijk we took the A17 to Brugge. On the A17 we took exit 5, at the roundabout to the right on to the Kortrijkstraat. The airport Wevelgem/Bissegem is on the LHS. The next roundabout go straight ahead, short after that turn left into the Luchthavenstraat. At the end of this street you see the tower of the airport; the DME is on top of it.
If you walk along the tower until the (low) fence you will see to the right the NDB just after the end of the runway.
