Hi Jose

thanks, good point, my explanation is that antenna works very well:-)
But the point i wanted to make was not about how i am heard. Does not really 
matter that much in my view, if rx capabilities do not match tx.
My firm belief is that it is perfectly possible having an optimized analog 
rx equivalent to the receive gain of 4*10.5m long yagis, can still allow you 
to hear and work qrp single yagi and 200-400w stations in cw.
My 2m array has 21.5dbd gain, 5 power dividers in each polarity, cables and 
connectors everywhere. My preamp is in the shack with a 0.5db loss added 
from the feedline, on top of everything else. This accounts for 0.95db less 
sun noise, not being mast mounted.
Still, it is perfectly possible to work qrp stations in cw random eme, 
provided that they give it a try. It is a myth that good rx cw eme results 
require a big array. I would say they require determination to make it 
happen:-)

73,
Jimmy SV1BTR
