For those types of proof, it is impossible to prove a
negative. It would be akin to the police knocking
on your door and demanding that you prove that you
are not a terrorist. The onus of logical proof is
upon the one who makes the positive assertion.

The one who has made the positive assertion is the one who has claimed that
by his new theory an antenna can be made that has a spherical radiation
pattern. I don't believe in the theory as he has laid out and I don't
believe that such an antenna can be built and demonstrated. My wager is in
respect of whether or not the protagonist can build and demonstrate such an
antenna to back up his own positive assertion.

It is in the nature of a challenge for him to take up if he wishes, and if
he does then his bet will be in respect of his positive assertion, but, of
course, he hasn't taken it up yet. If he doesn't take up the challenge then
nothing new is proved - whichever way you care to interpret that.
