"By common
expectation LPL and LR should have a propagation advantage over NY4A.
LPL and LR both have excellent stacked 3 or 4 element 40m yagi's. But
note how as the fourth mode is engaged, both LR and LPL fall off
because they are not cleanly engaging the mode, most likely because
the increasing elevation angle is starting into a notch in the yagi
vertical pattern.  Also note that NY4A carries the best signal for
most of the 24 hours. This is an evaluation of the NY4A 40 EU quad vs.
known excellent installations that is hard to argue with."

 From the ARRL results database, sorted by maximum 40m QSOs (after 
log-checking):

http://bit.ly/19YAF1f  don't worry Frank...it's OK  :-)

Rank            Call            40m QSOs

1.              K3LR            2000
2.              W3LPL           1911
3.              WE3C            1862
4.              KM1W            1818
5.              NY4A            1809

K3LR could be expected to have a higher total because of better prop 
to JA but the other 4 should have had similar propagation to EU, 
which would dominate their results.  There's more to this story than 
RBN spots from a single location shows.
