   yea thats right,  some times a single pass through the bead will do,
other times a couple of turns around the bead is needed.
Usually the Q of the bead will decide the correct number of turns..
If your receiver is fairly close I'd guess straight through or 1-2
turns..  (close to the panel end of the run)
If a longer run of wire  try them at each end of the wire run..

Engineers will give you the long formula,  I find it quicker to
just experiment..
Like some others have said,  you might tinfoil the receiver case
(just don't block the antenna)

The aim is to reduce the stray RF getting to the processor..
