FIELD: construction.
SUBSTANCE: invention relates to construction, in particular, to devices for protection of roof of ice crusts and icicles. In device for protection of roof of ice crusts and icicles containing microwave generator, microwave radiator and power supply unit, includes microwave valve and thermal unit. Microwave radiator is in form of rectangular waveguide with one open wide wall fixed on edge of roof, wherein output of microwave generator is connected to inlet valve, outlet valve is connected to input of rectangular waveguide, output of rectangular waveguide is connected to input of thermal unit, output of thermal unit is connected to input of power supply unit, which output is connected to input of microwave generator.
EFFECT: technical result of proposed technical solution is increased functionality of device and reduced loss of microwave power at heating roof edge with ice crusts and icicles.
