This is an example of a beacon we had to search for with a GPS. As the pictures will show the beacon can be found along small country roads. There are a lot of woods in these surroundings and so you will only see the beacon when you are very near to it.
The beacon is at the village of Ottenburg, about 4 kilometre North of Wavre. When coming from Wavre at Ottenburg, go right (Langerheide) towards De Tomme. The beacon is on the LHS of a dead end, Tommestraat.
People who are interested in broadcasting antennas are here in the right spot. The big Transmitter of Wavre is just a few kilometres from this spot.
