Have a K4KIO Hexbeam up at around 20-feet on the corner of a flat metal roof pointing at 290-degrees bearing (Europe, from Sydney Australia). Currently the Hexbeam is fixed to that direction as i don't yet have a rotator, and it's fed with ~25M of RG8.
There's also clamp-on ferrites at the feedpoint (supplied by K4KIO) and at the radio end.
Being pointed to Europe it works as i'd expect, but i also notice it receives USA as well which is off to the side of the antenna by a fair amount, when the band is open (on 40M & 20M mainly).
Even compensating for a very wide beam-width, the fact the Hexbeam is a 2-element beam, and not very high, it's interesting (to me anyway) it receives USA quite well when not pointed in that direction.
I work FT8 alot and can see via the pskreporter website this is the case. This happens regularly.
Was just wondering if this is a propagation phenomenon, a factor of it's current height, or something deeper i need to address?
