Topband: Air core chokes for 160m

[Vytenis Sciucka <vytenis.sciucka@gmail.com>]

Hello gyus,

I will need to make common mode choke for 160m "T" shape vertical for
my club station. I always used to think I should aim at 3000+ Ohms
impedance, but lately I found article at
http://rudys.typepad.com/files/160m-common-mode-choke.pdf which says
thousands of Ohms is not necessary here. Several hundred Ohms is adequate
and air core chokes are OK for 160m. Now I'm not sure what target to
set for myself.
What do you think about that?

Thank you
