[Elecraft] OCF antennas

[Don Wilhelm]

Well said Jim,

There is no way to obtain equal and opposite currents on the feedline 
with an offset fed antenna - they are a sure recipe for 
RF-in-the-shack.  As much acclaim as the Carolina Windom gets,  that 
fact is still true, one just cannot run high power with such an antenna 
- at low power the RF levels may be tolerable, but at high power, they 
can wreak havoc in the shack with RF all over everything.
