In 1985  the Lincoln Group bought WHAM , the 1180 khz clear in Rochester, 
NY. The WHAM base impedance was about 357 +/- j1100 ohms, which had been a 
problem for decades.  The WHAM tower was a 5 foot face 180-degree Blaw Know 
with a FM side-mounted on it, using a 90-degree bazooka.  Before we went to 
work on it, Bill Carr, our consulting engineer, suggested that I take a look 
at WWWE, 1100 khz in Cleveland, which also utilized the same model 
180-degree Blaw-Knox tower.  Carl Smith's consulting engineering practice 
was co-located with the WWWE transmitter site south of Cleveland and I made 
an appointment with Carl to see the site.

Immediately beside the base insulator of the WWWE 5-foot face Blaw Know 
tower was an approximately 30-inch triangular tower section which was 
grounded at bottom of the base insulator and insulated from the tower with 
approximately 6-inch power line insulators that Carl said he got from 
another project he was working on at the time.  The small tower was indeed 
bridged to the main tower at the 90-degree point. The transmission lines of 
several FM stattions, quite a few two-way antenna lines, and an UHF TV 
station were bonded to the base of the small tower, bonded at the bridge to 
the main tower and bonded to the main tower at the appropriate intervals up 
to their individual antennas.  This system had been operating for many years 
with incident, according to Carl.  Carl felt that the 30-inch tower 
effectively swamped the effects of the indiviual transmission lines and that 
adding additional lines really did not require any adjustment of the system 
of change of the WWWE base impedance, which was 51.5 +?j ohms.

Carl also showed me the horizontal FM bazooka that Cowboy discusses above, 
but honestly, I wasn't really paying attention.  The WHAM 90-degree stub had 
been "off" for decades, after replacing it and adding two STL lines with 
their 90-degree stubs, the WHAM base impedance was 51.5 +/- ?j.
