Ooohhhh!  I LIKE this!

But, why not just drop the directivity A&B category altogether.

Just use transmit EIRP (since directivity is already baked into
that figure) as the "category".  Allow the station to use any
receive antenna (Beverage, rhombic, loop, Yagi-Uda, etc).

Each band may have a different antenna, thus different EIRP.

But, if this can be solved if we were to use EIRP like a
multiplier, each band will come with your personal multiplier.

We don't need high/low power, good/crippled antenna categories at all.

We just need an EIRP mult and everybody in the contest is in the same
category. (Note I said category, and not class.  We know AA5AU is in
a class all by himself, HI HI).

If you want to cripple the multi-radio guys, just define the EIRP
as the sum of the EIRP of each radio/antenna in use.  Probably not
fair, since they don't transmit on two transmitters at the same time :-).

Hmmm, if EIRP is too confusing a number, how about just use Power
and antenna gain as separate mults (that you sum before multiplying).
Add power in dBW to antenna gain in dB.

OK, end of evil thoughts...
