1230 is not 225 degrees, more like 215.

1400 is also not 225 degrees, also more like 215, but it is diplexed  
with 550, and it has a ground system sized for 550, so what would  
normally be a tower with an efficiency of about 420 or so has an  
efficiency of 440 mV/m/kW at 1 km, which is the efficiency of a 225  
degree tower.
