Plus, you can't count on good data with only a few data points. Call TEST
or CQ on a different frequency a few minutes later and you will very likely
get different data. I've done extensive antenna testing using RBN, and,
from experience, I can tell you that to get a real handle on antenna
performance, you need many (hundreds) of data points over a few days, and
you need to look at the data statistically.
