Typical SWR meters are affected by any CM current that is present, and
because the CM signal is a standing wave it can cause the meter to read
differently for different cable lengths. In fact if someone ever reports
to you that their SWR changed significantly when they changed their coax
length, CM current is one of the likely "suspects".
