[TowerTalk] Best coaxial to make Chokes

[Dan Hearn]

Hector here is the information you requested. The coax wound chokes are
self resonant in the measurements and in my opinion will be detuned by
attaching coax feed lines and proximity to the boom of an antenna. Also
they are not very good for multi band antennas. It is possible to make far
better multiband chokes using ferrite type 31. Lots of info on K9YC web
page. I have built and measured a number of them and they work great.
