Mobile mast, in particular for supporting aerials for radios, television and the like, of which mast a first part is mounted pivotably on a supporting column which is arranged on a vehicle in such a manner that the mast can be moved from a virtually horizontal position on the vehicle into a virtually vertical position. The mast comprises a second part which is connected in an articulate manner to the first part, and said second part displaceably supports a third part which, in turn, telescopically supports a top, fourth part which bears the aerials.
