Contrary current flow within a radiator
Frank, I am not saying he is not credible but he is part of the older
generation and there was not enough detail supplied to determine
whether I accept it on trust. When the antenna programs
throw out the yagi in favor of arrays or radiators in equilibrium form
should we throw it out in favor of conforming with the past? Yes,the
article is in line with what the older generation has lived with
but the new generation have more tools and information than the
present dying generation.
Problem with present day authors is up against the "publish or
perish" format regure references to prior papers in quantity to
provide legitamacy to any new papers, without which they will have a
hard time publishing. Greasing the wheels of fellow contributers or
white paper authors is much preferable to declaring those who judge
are in error. Frank, a lot of the theory of antennas is either based
on vanishingly thin radiators without regard to room required for eddy
field and in some cases with transmission lines where it is possible
to get three different current flows together with a closed circuit,
yet we are now protecting the idea of non closed circuits where the
current flow
is on top of each other. No wonder it is said over the last 100 years
that we don't fully understand radiation especially when it takes over
70 posts on how to make a cantenna from a panel of experts

This is so amusing. Those who don't appreciate knowledge thus far, probably
don't know it. Those who are desperately hoping for a revolution might just
have a ulterior motive or agenda.
It is interesting to note though, that it takes a lot of PhD's to design
something so that impoverished people (often children) can have a bowl of
rice every day to build the technology. Also, the environmental disaster
that is created by throwing away "gadgets" every 6 months to implement the
latest technology. I wonder if the Liberal academic establishment is in
touch with the environmental disaster they are creating so that we can all
be enslaved to the global neural network.
The cantenna posts are amusing, in that no one even brought up the
transition from the connector to the resistor element, or adequate thermal
conductivity between the oil and the outside air. The biggest problems
revolves around these issues. Starting with how long must the transition be
to allow adequate oil convection flow. The answer to all this can be found
with the high power Bird loads that have a smaller oil area but use large
radiating fins, or better yet, A chip resistor array directly mounted to a
large fin area.
