WQPT-TV is a PBS member television station serving the Quad Cities area of northwestern Illinois and southeastern Iowa.
WQPT’s HPTV-PRLX-U16 27.5kW transmitter consists of a single rack cabinet equipped with 16 UHF Asymmetric Broadband Doherty final amplifiers that provide the highest power density in the industry.
The PARALLAX transmitter was delivered complete with dual EXACT-V2 ATSC exciters (in main / standby configuration) and the liquid cooling system. COMARK also supplied the new RF mask filter system and interconnected coax feed into the facility’s existing RF channel combiner.
The shipment, offloading, and placement of the new equipment into the existing broadcast facility was managed by COMARK. After the mechanical installation of the new transmitter system was completed, COMARK’s field engineer turned on the new transmitter, performing the complete proof-of-performance testing towards the end of March 2021.
“The team at COMARK provided a complete solution to replace WQPT’s older UHF transmitter system as part of the station’s plan to increase their ERP”, states Joe Turbolski, VP of Sales and Marketing for COMARK. “The new transmitter installation went as planned, having the new equipment installed in about a week. We’re pleased to work with WQPT to provide one of our PARALLAX transmitter systems that ensures better signal coverage to their viewers.”
