"Sivash-0,25DM" Antenna

"Sivash-0,25-DM" broadband stand-alone one-bay multi-input panel antennas are designed for operation with analog and digital TV transmitters of  low power. The main feature is a capability of direct connection of 1 to 4 transmitters (3+1) to MSS 4x4 antenna unit (Matrix Split System) without asing any additional equpment. The application of combiners, dividers and reservation systems is not justified when feeder lenght to antenna is small (50-80 m) and using of common main feeder in non-value-added.

frequency range470-862 MHz
гoverall dimensions (A*B*C)2215x700x700 mm
max. input power0,5 kW
TV bandsIV-V
