Did you do any others? I'm guessing that this was done on the Decibel 
antenna range, maybe?

Back when we had to submit an antenna pattern in order to get a repeater 
license for the ham bands, I mounted four elements of a DB-224 directly on 
one leg of a Rhon 25 tower and mounted the two tower sections on an antenna 
test pedestal and ran the pattern.  With the antenna sections directly in 
line and pointed away from the tower, we had 9 dB gain in the favored 
direction, 6 dB gain at plus and minus 90 deg, and 3 dB gain off the back 
side of the tower.

The plot was perfectly round with the 3 dB offset for the center point of 
the plot.
