TEM Opera Plus 2000W FM StereoMono MPX Transmitter

OPERA plus 2000W FM 87,5÷108MHz transmitter uses 2x1250W amplifiers with 6^ generation LDMos technology, practically unbreakable.

The technical solutions adopted by our engineers are focused to assure energy saving (among the lowest) and high reliability. Settings, protections, telemetry are totally microprocessor controlled. The installation and the maintenance of the equipment are respectively very fast and easy.These fully protected transmitters are indicated for use in unmanned stations.
