[TowerTalk] Balun Recommendation

[Steve Hunt]

Tod,

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".
