Last evening a couple guys ran a test of signal strength of the two antennas 
with several stations separated from 10 to 200 miles apart.  The dipole was 
about 2 s units stronger at all locations. 

I suggested that the screwdriver be laid over horizontally to then compare to 
the dipole.  Alas, I forgot that a low horizontal antenna suiffers efficiency 
so that laying the screwdriver over at its typical mounting height may not be a 
valid comparison?

They plan to run the test again tonight but with the screwdriver horizontal  
but at what height I don't know.
