Theoretically, that's wrong, but it's the measurements that count, and 
given the effect of the metal tower elements on the radiation pattern, 
it's possible they found horizontal polarization would pass muster where 
circular didn't.

But my gut feeling is they were racing the clock, and had they found the 
NIR over the limit they would have just dropped the power.
