No, I think in order to equate the two antennas performance you'd have
to have the same boom length. Comparing an 18 foot boom antenna (the C-3) to
a 32 foot boom antenna (the XA) is not only a case of apples and oranges but
also is downright misleading in terms of espousing accurate information and
comparisons.
Otherwise, your well thought out comments are always welcome and
appreciated on TowerTalk.
