The 4el yagi is on top of the tower at 80 ft.  The 8 el yagi is at 30ft
fixed to EU.  So yes, there is sometimes some angle optimization that would
explain the larger than expected gain difference.  But it ALWAYS beats the 4
el yagi.  And not having an antenna range available, it's a good sanity
check that the antenna is performing to see always 1 and sometimes 2 S units
of improvement.

 

HFTA says that the 30 ft position should add 6 - 8 dB at its peak to Europe
but often its equal to or a few dB less than the top position.  I have never
seen the 8 el less than an S unit louder than the 4 el.
