Kelly Boswell KA5MGL reports 43 beads give minimal improvement. -- 43
Mixture is the best for both 2 and 10 meter RFI. If by "minimal effect" you
mean a small improvement then more beads or several turns through one bead
should give further improvement. You may need them on both rotator wire and
power cord to see an improvement if the RF is entering both ways. Also, is
the control box metal and grounded? Is there a glass meter face that is not
shielded? Is there RF in the shack? If so treat the antenna cable. -- Jack,
