A mast radiator (or radiating tower) is a radio mast or tower in which the metal structure itself is energized and functions as an antenna. This design, first used widely in the 1930s, is commonly used for transmitting antennas operating at low frequencies, in the LF and MF bands, in particular those used for AM radio broadcasting stations. The conductive steel mast is electrically connected to the transmitter. Its base is usually mounted on a nonconductive support to insulate it from the ground. A mast radiator is a form of monopole antenna.

  • Ein selbststrahlender Sendemast ist ein Sendemast, bei dem die gesamte Konstruktion als Antenne wirkt. Er wird häufig als Sendeantenne für Lang- oder Mittelwelle eingesetzt. Gegensatz ist der Antennenträger, der nur als mechanische Halterung für die in seinem oberen Abschnitt angebrachte (relativ kleine) Sendeantenne dient, etwa für UKW-Rundfunk oder Mobilfunk. (de)
  • Un traliccio di trasmissione (o torre trasmittente) è un' con la caratteristica principale di impiegare l'intera struttura come antenna. Quest'architettura è comunemente usata per impianti che irradiano nella gamma di frequenze che va dalle VLF alle MF (queste ultime più conosciute fuori dall'ambito radioamatoriale come onde medie), in particolare per la radiofonia in modulazione di ampiezza. La base è fissata su elementi elettricamente isolanti a bassa capacità, spesso di porcellana, per isolarla dal terreno. Un sistema di questo tipo è comparabile ad un'. (it)
