ARRT-Antenna

An ARRT-Antenna (Cyrillic: АРРТ) is the designation of a common type used on many AM broadcasting sites in former Soviet Union, Bulgaria and Albania.

It consists of a cage antenna which is mounted around the lower parts of a mast radiator insulated against ground and insulated from the mast.

The mast and the cage antenna are fed separately.

The ARRT-antenna allows a radiation pattern with less skywave radio propagation and is more easily realizeable than a mast divided by insulators.

Such antennas are used e.g. at the mediumwave masts of Bolshakovo transmitter.
