Hi Filipe
Zero , you should use material #31 or #77 , The core you have is not good
for low bands.

Subject: Topband: Commond mode choke for Beverage
Hi guys,
I am about to add a common mode choke to isolate the antenna from its
feedline to each of my beverages and I only have FT240-61 ferrites. My
question is how many turns should I do on the ferrite using RG58 (all my
bevs are fed with RG58). Also should I put the choke near the 9:1 balun or
near my bev switching box?
Thanks in advance.
