[TowerTalk] 1. Ferrite, 2. Polyphasers

[Dan Atchison via TowerTalk]

Two questions for the group.

1.  I'm making RF chokes out of 2.4" ferrite cores, mix 43 and mix 31 
material.  Is there a maximum limit to the amount of ferrite I should use?

2.  Are there any advantages to using more than 1 Polyphaser in a feedline?

Thanks,
Dan
