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).
The ALP Series, with a medium cardioid azimuth pattern, UHF television antenna is almost finished packing and will be leaving to begin service as an auxiliary antenna for a Full Service TV station. This is a low power model which is rated to handle up to 5 kW average power. The medium power version handles up to 10 kW.
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.
ERI maintains an inventory of emergency stand television antennas to be used during new antenna installations and to get stations back on-the-air in emergency situations. The antenna pictured is a broadband UHF panel antenna that has 7.5 kW average power handling capability and includes a mounting with integrated leg mount brackets. This UHF television antenna is horizontally polarized and can be used on any RF channel for 14 to 51 (470 to 698 MHz).
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.
This ERI Model MPX-8C Medium Power ROTOTILLER® FM Antenna is tuned and painted and heading for packing. This FM antenna is bound for Fairbanks, Alaska, to be used by KUAC-FM, the University of Alaska-Fairbank’s NPR member FM station. The antenna will be installed on Ester Dome near North Pole, Alaska.
