forestrunner,
in general you don't want to choke the common mode currents anywhere but at the feed point because they will still travel down the shield to wherever your choke is.
i can imagine that the 5 or 6 beads didn't do much because there just wasn't enough of them.
you really need to do like a foot and a half to two feet worth to get the desired effect.
yes, you can also just wind the coax into a choke at the feedpoint, but that can be logistically difficult because of headliners and other obstructions.
however you get there, the idea is to stop the common mode currents right at the feedpoint.
anywhere past that, and you have coax shield as part of your radiating system.
im just throwing out ideas, not knocking what you have in there now.
if you haven't done it already, the next biggest change you can make in your receiving and transmitting range is to bond the different parts of the vehicle together with copper strap.
i couldn't believe the difference this made in my S10 pickup.
receive was quieter, but i could hear further, as well as my signal reaching out a bit further.
