Tripelo, thanks.
I am happy that you have given me this info
My head is spinning but I will recover.
Here are the Ferrite cores ordered from Mouser:

Man, they are so very careful about the packaging. I guess they are very brittle.
Are you thinking I only need two Ferrite cores or, the more the merrier?
At least one at the junction and at least one at the 1/4 wave length, 5.5" down?
I have 10 of each of the above.
I need to stop and get some more shrink wrap
