Full Service UHF television RF system now in packing for shipment

This RF system includes two (2) 6-section UHF band pass filters and will be part of a two-cabinet UHF television transmitter that will operate with a transmitter power output (TPO) of 30 kW. The two individual power amplifier cabinets will operate at 15 kW each and each have their own 6-pole band pass filter at the filter outputs a 6-inch 3 dB y-brid will combine their output to achieve the 30 kW total power required to achieve the station’s authorized effective radiated power (ERP).

Setting the First TRASAR® UHF Television Antenna for WDRB/WBKI, Louisville

The new ERI tower for Block Communications is nearing completion. ERI has manufactured and has almost completed the installation of the new 945-foot tower for WDRB and WBKI serving Louisville, from Floyds Knobs, Indiana. The structure will have an overall height of 1,000-feet when the two top mounted, elliptically polarized, UHF television antennas are installed.  The tower is topped with a T-Bar which supports the two antennas with centers of radiation at the same height above ground level and with a separation of 30-feet between them, to minimize distortion of each antennas’ horizontal plane pattern. In addition to the two top mounted main antennas the tower also supports an auxiliary antenna for each station which are side mounted between 775 and 890 feet above ground level.

Four Station FM Channel Combiner in Final Assembly

This is a four (4) station constant impedance FM combiner system for four Full Service FM stations. The operating frequencies of the FM stations in the combiner system and collocated with the Master FM Antenna these four station will use are all closely spaced channels so the band pass filters in the system are all four-pole and include optional non-adjacent coupling loops to provide additional suppression at the band edges of each filter bank while reducing group delay variation.
