Hi Ed,

Aside from the charged particles introducing noise, there is no
difference. If charged particles is the noise, then I offered a
solution that reduces the issue of antennas to: no difference.

If it relates to corona discharge, then you may have to ask yourself,
what about the difference between corner fed and center fed loops
(this made a huge difference to HCJB in Quito).

Just tossing out the term "low noise" is in itself a reliance on hopes
and wishes to sort out what the noise is. This is because forcing the
discussion into more context invariably reveals the old nostrum of
magnetic antennas being immune from electrical noise. Then we get
into all sorts of equivocation which in the wash inevitably reduces
to: no difference.

Point is that a loop reduces that "noise" where a dipole allows the
"noise" to build up until it arcs across the coax connector which
causes an extreme amount of "noise". One night in AZ, my PL-239
connected to my IC-745 was arcing so loud that it woke me up. I
disconnected it and tossed it on the floor. A few minutes later,
the carpet was smoking.

Aside from the arcing waking me up and the burning of the carpet,
there was no difference.
