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.
