20m Vertical vs 20m Fan Dipole - Simultaneous WSPRs

 When I tested the 40m Fan vs 1/4 Vert  the Fan came out nearly 5 db better.  I was expecting the dipole to be 3 db better broad side with a deep null off the ends but it really wasn't all that dynamic. 

 Overall the 20m 1/4 Vert with 8 radials did better then the 20m Fan Dipole by about 3 db. 

The graph below is simultaneous spots ,  LDP the Fan  subtract IMI the Vert


Spots Map both are Green Dots,  LDP the Fan is Blue and IMI the Vert is Red 



Its really interesting when you look at simultaneous spots more the 4,000 km away.










The KH6 is more or less off the end and the EU stations are broadside.
