The reference antenna was a Hy-gain TH2 ... not a quad.  Some of the
antennas tested were rather large quads.

Although the reference antenna antenna was on a trailer mounted
crank-up, the big problem with the study was that there was no
control for tower height of the fixed station antennas and take
off angle issues severely clouded the data.
