Late this morning I called CQ on 40M; had a mobile from Massachusetts come 

On the dipole 60Ft AGL he was in the S5 noise level
On the NVIS (8, half waves, four fed over four reflectors) he was in the noise 
On the 3 element full size yagi ( 48ft boom) he was in the noise S4

For fun I parallel all three antennas.  With this scenario his signal went up 
to S7 a and the noise was S5.  He reported that my signal went from S9 to 

Must be a hurricane in the F2 layer this morning.  It seems that this morning 
the only way to optimize the path was to utilize an antenna system that has 
multiple major lobe take-off angles... 20/50/90 degrees. fun stuff. 

I just play with these antennas... Are there any experts or Antenna engineers 
on the list that can clarify this morning's scenario?
