Hi Pete,

I'm not sure that the transmitting antenna and receiving antenna 
limitations that Dean assumed does not also affect the numbers.

Maybe someone else knows, but didn't Dean assume low or 
modest antenna heights?

I know the angle on 160 is a heck of a lot lower than most 
predictions seem to indicate, because my high dipole kept getting 
better and better the higher I raised it. It never has gotten as good 
as a 200 ft vertical, even though it is 300 feet up.
