ARRT-Antenna
ARRT (Russian антенна с регулируемым распределением тока ) is the name for a type of antenna used in many major Russian channels for long and medium wave.
A Arrt antenna consists of a vertical cage antenna coaxially mounted on a grounded or insulated from ground transmission tower. In the latter case, the cage antenna and the mast can be individually fed with high-frequency energy, which can be used to build an effective anti-fading antenna.
The translation of the title is ARRT antenna with adjustable current distribution.
