TSG Commissions 2 R&S Transmitters

Technical Services Group (TSG) has commissioned two new Rohde & Schwarz (R&S) transmitters for WMBC-TV at One World Trade Center.

WMBC-TV is the latest broadcasting tenant for the Durst Organization on the One World Trade’s master antenna system.

Last year, Radio Frequency Systems (RFS) extended its existing antenna and combiner infrastructure at One WTC, which allowed WMBC-TV the ability to upgrade to ATSC 3.0 broadcasting. Owned by Mountain Broadcasting Corporation, WMBC-TV is an independent, full-power television station serving the New York metropolitan area, which is the largest Nielsen DMA market in the United States.

As the owner representative and design-build contractor for the project, Advent Industrial Corporation, together with Technical Systems Engineering and Marc Musgrove of the Durst Organization, collaborated on the design of the RF and support systems for WMBC-TV. Advent Industrial Corporation prepared the tenant space and integrated the electrical, mechanical and RF systems into the building’s master state-of-the-art broadcast infrastructure. Bo Hoover, CEO of TSG, said Advent was instrumental in facilitating and coordinating all the skilled union trades people for the project.

This project marked a return to One WTC for Advent Industrial Corporation. AIC had previously built a significant number of the major TV transmitter facilities in the original North Tower prior to 9/11, and was instrumental in the post 9/11 emergency return to on-air broadcasting at the Alpine Tower.

Once the physical components were in place, TSG worked closely with RFS’s Todd Loney, who managed the filter tuning and optimization of the master combiner, while TSG handled the commissioning, startup, and proof of the remaining system equipment. WMBC-TV is broadcasting from two new R&S®THU9evo-40 transmitters (main and auxiliary), which can be used seamlessly with either the upper (RFS PEP96) or lower (RFS PEP40L) antenna main and auxiliary systems at One WTC.
