The 160m CM choke needs to resonate lower in freq. It requires more cores
to shift the res freq down.

I shunt feed my tower for Topband. Presently using a Comtek 100 bead balun.
After reading K9YC's article on baluns it would seem that a stack of five
#31 cores with 7 turns of coax would be a better balun.

I measured the Comtek bead balun on 160m and found there is low choking
resistance.
I use the K9YC design with good results, whether it will make any
difference in your antenna system is something you will need to try.
With more than 5x the choking resistance with the K9YC 7T on 5 #31core
I shunt feed my tower for Topband. Presently using a Comtek 100 bead balun.

Would I notice an improvement in any way by switching baluns?
If the answer is I would
