Tony,

I strongly advise you to use the binocular core. Complete winding details 
are available at:

Click on the "rotatable flag" topic.

I now use binocular cores for all my RX antenna projects, including Flags, 
Pennants, K9AY loops, and beverages. Those who I have convinced to use 
these cores, have not gone back to toroids.

Goos luck.
