Stations broadcast DTV with Dielectric


Dielectric's solution for KTBS included the use of a combiner and splitter that allows the stations to share a single 8in transmission line, thus minimizing the tower modification requirements.

ABC affiliate KTBS-TV, in Shreveport, LA, has installed a new antenna, transmission line, and tower modifications from Dielectric Communications. The purchase has enabled partner station KPXJ, a UPN affiliate, to share its tower for greater cost efficiency and to improve reception. Dielectric's solution included the use of a combiner and splitter that allow the stations to share a single 8in transmission line, thus minimizing the tower modification requirements.

The project helped KPXJ achieve several goals: the station 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.
