The invention relates to an antenna mast comprising mast portions, placed one on top of the other, in the precast reinforced-concrete construction method. In order to form a spigot and socket joint, the mast portions have, at their neighbouring joint ends, a socket, on the one hand, and a plug-in end, on the other hand. In the case of a plug-in end which has been plugged into the socket, a pot-like pressing-in gap is formed between the socket and the plug-in end for receiving a setting filler to be pressed in. As a result, a corrosion-free joint formation is achieved. <IMAGE>
