Hello Bill,thanks for your comments.

Of course I don't know but in the case of 160m I was comparing both
antennas in different times for at least 2 weeks so in different propagation
and I suppose I can be sure the shunt feeding is better.
I know /as you told me before/ it happens that especially near sunrise/sunset
we have propagation with high angles but I have too many antennas on one tower
to have so many systems for each band /on one tower I have Yagis,Sloper for 80m,
sloper 160m and 2el wire delta for 40m/ so I have to choose...

I suspect this is a reason on 80m...I'v been sure it will be similar "success"
as
with 160m but its opposite.I was trying with JA's also in different time /but
not so
long as on 160m/ ,so I suppose its not a case,additionally with omega matching
I have very narrow band on 80m ,so with sloper its much easier ...and I hope
better.
