A mast radiator (or 'radiating tower') is a radio mast or tower in which the entire structure functions as an antenna. This design, developed around 1930, is commonly used for transmitting antennas operating at low frequencies, in the VLF, LF and MF ranges, in particular those used for AM broadcasting. The metal 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.

  • A mast radiator (or 'radiating tower') is a radio mast or tower in which the entire structure functions as an antenna. This design, developed around 1930, is commonly used for transmitting antennas operating at low frequencies, in the VLF, LF and MF ranges, in particular those used for AM broadcasting.

  • Un traliccio di trasmissione (o torre trasmittente) è un'opera artificiale per telecomunicazioni 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 sua base monta un elemento non conduttore di elettricità per isolarla dal terreno. Un sistema di questo tipo, infine, è comparabile ad un'antenna a monopolo.
  • 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. Bekannte Vertreter der Bauform mit Einspeisung über die Pardunen sind die Sendemasten in Aholming und Donebach für die Langwellensender des Deutschlandfunks.
