Hello guys,


I have been trying to model a Dual Output K9AY I.e. taking another output from 
where the termination is normally placed. Then combine the two equal amplitude 
outputs with a small phased shift:

10 deg. at 500kHz; 20 deg.at 1MHz; 30 deg. at 1.5MHz, 37 deg. at 1.85MHz. 

This provides the typical K9AY pattern. However, the gain 8dB higher at 1.85MHz 
and 22dB higher at 0.5MHz compared to the K9AY.

I have yet to verify the model. However, does the model change stack-up??
