KPXJ broadcasts DTV signal with Dielectric antenna
ABC affiliate KTBS, in Shreveport, LA, has installed a new antenna, transmission line from Dielectric Communications. Tower modifications were also completed to allow station KPXJ, a UPN affiliate, to share its tower for greater cost efficiency and to improve reception. Dielectric supplied a combiner and splitter that allow the stations to share a single 8in transmission line, thus minimizing the tower modification requirements.
With the help of Dielectric engineers, KPXJ replaced its former analog antenna with a digital UHF antenna, and with the move to the much-taller KTBS tower, the new antenna was elevated from 450ft to 1600ft, greatly increasing KPXJ's coverage area.
KPXJ purchased Dielectric's TFU-30DSC-R S180 antenna, which provides an average power rating of 40kW. The side-mount TFU-series antenna was installed on the existing tower with only minor modifications. According to Lauren Ostendorff, president of KPXJ, the work completed by Dielectric turned a cost-prohibitive DTV challenge into a cost-effective, high-performance solution.
