Does anyone have any thoughts on what is going on here, and whether
anything can be done to improve the situation? I have also considered
using a Boomerang instead, as this can be centre mounted and is designed
to work stood off from a pole similar to my situation.Again, any thoughts
?


Offhand, it would seem feedline radiation is ruining the pattern. Skews
the pattern up off the horizon. Not that your coax length is nearly a
1/2 wave now. It's probably acting as part of the antenna. Try a
choke, ferrite beads, etc, below the feedpoint. MK
