[RFI] Bead Size for RG-8X Choke Balun?

[wd3q@erols.com (Eric Rosenberg)]

After reading lots of material on choke baluns (including the
piece by K3LR in CQ Contest magazine), I'd like to put on on
the RG-8X feedlines for my antennas.  

What is the correct size (model #?) for these?  The surplus ones
I've seen seem awfully small (as if for RG-58)

Thanks in advance!
