I almost bought some, then found the shipping cost was $35 + some other costs.
60 x 38 x 20mm, means they are 2.35" OD x 1.49" ID, 0,787" thick. I calculate about 27 or 28 turns of 660/43 Litz. It would be nice to know the A sub L. I guess someone needs to buy some to find out.

What is the diameter and thickness?
I've used broadcast band baluns that were larger diameter and closer to a round thickness in a couple circuits. Have not experimented with them much but results were good.
