20m Fan Dipole vs 1/4 Vert

 Comparing  these two antennas it was alot closer results each having its own advantage.  

The 20m Fan Dipole is at the top of the hill runs from about 260 deg to 130 deg favouring EU and AUS,  40 and 220 deg broadside.   The 1/4 Vert with 8  radials is just behind the house on the side of the hill with a GP tilted towards 200 deg.  











The fan Dipole is LDP ,  the Vert is IMI.  The fan favours EU and the Vert favors in the direction of AUS.  

The reason being is that the vert is shadowed by a big hill looking toward EU and the ground plane is tilted towards AUS.   The fan Dipole has clear LOS both directions.    

Looking out greater then 3800 km ...simultaneous spots
