Today Hilko PC1CP, Adriaan PD4AK, Thomas PA1M, and Jan PA0VAJ helped to lift de fourth tower. I had mounted the SteppIR in the tower when it was on the ground. I had mounted one side of the elements on the ground. We made a working platform from 4 meters high. Then we lifted the tower and when it was five meters from the ground Hilko went up the platform and mounted the other 4 fiberglass poles. After that we lifted the tower in his final position.
