Noise level between two ant types

Quads are a lot less noisy than Yagis when the wind
is blowing in the Arizona desert. Quads have a DC
short across the feedpoint that reduces noise from
static buildup.
Virtually all Yagi's have dc paths to discharge the elements.
The primary reason a quad is quiter is it has no sharp protruding ends
that are sticking way out in the air.
As a matter of fact if you research the quad, it was initially used to
eliminate corona at radio station HCJB.
Try this test, wire a small 2.5 MHh RF choke across your antenna and
check the before and after noise levels. They will not change.
