Gentlemen
I have in the past alluded not only radiation from a straight element but
also the ADDITION of radiation
occuring from a bent element. Nobody has commented on the authentisity of
this statement and I have not come acros anything in my own collection of
books.
Now my present antenna consists of various loops connected in both a
clockwise and clockwise radiation form such that the circular polarisation
cancells leaving pure vertical polarisation.. The loops are separatred in a
way that intercapacity of the spiral loops is reduced as well as circular
cancellation All of this is based on my gut feeling that R.F.current flowing
around a circular radiating element. What I ask for for those who have a
deeper background of R.F. is verification of my assumption
that extra radiation becomes available.

It does not. If you apply 100 watts to an antenna, 100 watts is
available to radiate, less any amount dissipated as heat. This applies
to EVERY antenna, from a rubber duckie to a zillion-element Yagi with a
boom you can walk on. No bending, adding of elements, supergain, loops,
or magic will give you any "extra radiation" above that. All you can do
with all the possible tricks there are is to concentrate some of that
100 watts in some directions at the expense of others.

Appreciate any comments on this irregular aproach as I cxannot find guidance
in the books.
A serious question regarding added radiation from an element in the hope
that insight is provided even tho it may expose the fallacy of my aproach.

My statement above is based on the law of conservation of energy, which
it sounds like you're trying to violate. If you think it's possible,
you'd make a lot more money by putting your effort into developing a
perpetual motion machine.

Thanks in advance
