Well I thought that braided wire was not good to use.
I have heard that braiding for instance must not be used for a grounding
wire presumably because of poor electrical connections where the wires
cross..

He is using coax presumably for the braid to rediate. I suppose there is

some
benefit to connecting to its inside???

Hi Art, I think the braid is connected to the inner conductor in an

attempt
to reduce I^2*R losses. In small loops, that is a problem. As far as
increasing radiation, it should have the same effect as changing from a

smaller
diameter wire to a larger one. You get less loss, but does the inside of

the
smaller wire radiate less than the inside of the larger wire?
One thing that caught my eye was the use of 300 ohm line for the

capacitor.
The high voltage high Q cap. is another problem with small loops.
