Yes Richard the literature does abound with bent antennas, even yagis to
obtain a particular performance.
I know that there are "curls" in fields and waves analysis
but I view travering a circle at a constantspeed as generation of a force
vector as in centrifugal force which I probably falsly have placed in the
radiation category.
If I am incorrect I need to understand why so that I can rebuild my thought
processes. Modelling the antenna
shows insights that i had not realised before causing me to make an actual
antenna for follow up.

Hi Art,
Extra? From where? What is the source? If it is the same source,
then it is not Extra, but simply managed to fit a need. In this sense
you still have to balance the budget of what you got, and what you
radiate and what you lose (to heat). The budget does not allow
Extras. The budget does however allow you to transfer balances as
long as you maintain the same total. In this sense, it is like
stacking elements with the correct phase relationships to move
radiation that would have gone to the clouds, towards the horizon.
You are still radiating the same power, but the relationship change
has netted more of it going in a direction more suitable to your
needs.
Now, as to the matter of bends in the antenna doing this; then the
literature is rich in examples to this matter. The Franklin antenna
comes to mind. It has lots of bends specifically tailored to create
this budget shift. It has been around for 70 or 80 years?
