The Maxiva™ VAX with PowerSmart® 3D VHF air-cooled transmitter delivers the highest AC to RF efficiency available today for TV and DAB broadcasters.  Based on the innovative GatesAir VHF transmission platform, the new Maxiva VAX transmitter incorporates ground-breaking technology to deliver unrivaled power efficiency, an extended power range and a full operator feature set. These capabilities, along with flexible system configurations and a very compact design, all add up to save money, time, increase system reliability and provide a solid foundation for broadcasters to build their network.

PowerSmart 3D technology delivers superior operational efficiencies through fully broadband, single-amplifier designs that simplify installation, improve performance, and streamline ongoing operation – including maintenance.  This comes courtesy of a modular design that eliminates tuning, minimizes overall labor and reduces spare parts to one set for an entire transmission network.
