This may be an ironic inversion of the condition we had years ago, where
antenna manufacturers claimed all kinds of gain numbers for their
products because they knew they were essentially unverifiable. Now, with
the new policy in place and a better means of verifying antenna gains
through modeling software, it is almost as if no one-- or, rather, very
few-- want to step forward and put their claimed antenna gains on the
line. Interesting.

It looks like ARRL has done its job well, at least to weed out the
ridiculous numbers from the rest.
