Specifically suited to produce good impeedance for lower band common mode chokes.

 

This is an ideal core for a common mode choke for Top Band 160m and Short Wave receiving due to its high initial permiability.

 

These cores are large at 2.9" so they are great for winding coax through the middle of the core.
