GatesAir, working closely with The Durst Organization, has completed the relocation of a renowned New York City broadcaster to One World Trade Center nearly four years after its opening.
The complete installation includes two GatesAir ULXTE-80 liquid-cooled transmitters (broadcasting at 47.2kW (pre-filter) TPO). Each transmitter is equipped with a software-defined Maxiva XTE exciter, that can operate in combined or main/backup configurations.
The One World Trade Center Broadcast Center is located on the building's 90th floor. The two companies have also enacted a full preventative maintenance strategy that covers post-sales support, spare parts delivery and other technical support needs. The facility houses all new RF systems (including signal combiners), antennas, emergency generators and other equipment to support local broadcasters.
The center has been designed for optimal energy efficiency, including LED lighting and a large water plant. The latter was added to encourage a liquid-cooled transmitters thereby minimizing air-conditioning loads, power consumption, and related utility costs.
In addition to its liquid-cooled design, the ULXTE incorporates the latest LDMOS RF devices to reduce footprint, weight, and optimize efficiency and power gains.
GatesAir has raised overall ULXTE transmitter efficiency to 45 percent, and improved transmitter output power by 20 percent. The result is a significant operational benefit allowing broadcasters to drive more power from a smaller transmitter, substantially improving cost per watt.
The ULXTE is equipped with GatesAir’s software-defined, ATSC 3.0-ready Maxiva XTE exciter and the company’s latest real-time adaptive correction (RTAC) software. The RTAC software is instrumental to over-the-air performance, dynamically and continuously and adjusting modulation error ratio (MER) and shoulder levels to minimize unwanted RF that affects signal integrity.
