Nice chokes ready to go in many different configurations.  I've been 
using them for years.  Very well built and quick to ship.

I read the article by K9YC and concluded that the best approach wold be to wind RG8X around 6 Fair-Rite toroids made from type 31 material and 2.4 inches in diameter.  The big problem is they are listed at over $17 each from the distributors.  I will need 18 of them eventually.  6 each for this dipole and two more yagis.  That’s a large price tag, but still cheaper (and better performing) than the commercial units available, according to K9YC.

It might work out that I could make a large purchase and offer kits of toroids to the group.  I’m not looking to make money.  I only want to have a good choke at the lowest price I can find.
