Default Is It double bazooka less noisy?

No. It makes no difference at all.


It certainly made a difference in the Arizona desert under
conditions that cause precipitation static in a dipole with
no DC path between the elements. Many hams have direct
experience and have reported it. Here is a discussion of
such over on eHam.net.

If you have a static build-up problem all you need do is install a leak
resistance or a suitable RF choke to ground. One should have that in an
antenna anyway.


But a lot of hams don't know that and run their dipoles with
the two coax conductors DC isolated from each other. I'll bet
the "plain dipoles" being described by lu6etj as noisy don't
have a leak resistance. The Double Bazooka is automatically
protected from static buildup between the elements as are loops,
and folded dipoles.
