Hi,

I am in the process of deciding on materials to use in making the new K9YC recommended chokes (thank you Jim!) for for my yagis, 4-squares and for EMI suppression purposes.

What I want to buy is:

31 material Toroids, I believe this would be Fair-rite part #2631803802 2.4" OD 1.4" ID rings
RG 142  Coax
RG 179  Coax
RG 400  Coax

Does anyone have any recommendations from whom I should buy these materials?

I see the 31 material toroids for ~ $9 - 10 if I buy 25 or so

RG142, RG179, RG400 vary enormously in price - and possibly also in quality. I don't know one manufacturer from another.

I would appreciate any recommendations/details as to whom you would buy from (or have bought from) and who you would avoid.

Also, what/who would you recommend for small boxes in which to house the toroid?

Tnx & 73

Bob, KQ2M
