[TowerTalk] Fwd: current balance in ladder line?

[Steve Hunt]

For me, distortion of the radiation pattern of a simple dipole or loop 
is the very least problem that CM currents can cause.

Much more significant is the potential for RFI, and increased noise 
levels on Rx, because the feedline has become an active element of the 
antenna system. It's usually easy to spot if you have the RFI problem; 
but the Rx noise problem is more difficult to identify, and many folk 
are unaware that they could potentially lower their noise levels by 
addressing the CM issue.
