Suspending the analyzer might be adequate for 6 meters, which is the
antenna under discussion. But I should mention for the benefit of the
general audience that it isn't adequate for 2 meters. Not too long ago I
heard from an EZNEC user who found a substantial difference between
modeled and measured results from a simple antenna. On my suggestion, he
added a simple wire frame representation of the MFJ 269 to his model,
and it made the model results much closer to his measurement. So in that
case the antenna analyzer itself was enough to substantially skew the
measurement.
