Dave and Ty mentioned using vertical polarization for triband tests.  This is
usually NOT recommended for HF antennas on a ground-reflection range using the
gain-transfer method.  As stated in the IEEE Std 149-1979 (Test Procedure for
Antennas), page 101:

"It is not practical to employ vertically polarized gain-standard antennas for
this purpose [87], since the power gain of such antennas at low elevation angles
is low, and varies drastically with the moisture content of the ground."

Antennas as Gain Standards, IEEE Trans. on Antennas & Prop. (Communications),
vol. AP-23, Mar 1975, pp 284-286.
