The height difference of 30 feet on ten meters is significant. Our test
of the C-3 shows that it has 2-2.5 dBd gain on 10M. All your comments show is
that at THAT time, on THAT band your results were similar. It's not a valid
evaluation of either antenna's performance.

Well, it's these anecdotal observations that we're trying to get away
from. They're not valid. Until you have data obtained from a standardized,
repeatable test - it don't mean a thing. That's why we are going to all this
work so that we can present some REAL on-the-air data.
